Abstract
BACKGROUND AND OBJECTIVES Wilson's disease (WD) is an inherited disorder with perturbations in copper metabolism and can cause multiorgan damage. This study aims to explore cardiac findings mainly based on electrocardiography (ECG) in WD patients. METHODS We retrospectively enrolled adult patients who were diagnosed with WD between January 2011 and December 2020. Demographic and clinical data were collected and reevaluated. RESULTS A total of 126 patients were included. There were 71 men and 55 women. The mean age was 27.2 years. Ninety-nine had hepatic presentation as the initial symptom and 27 had neuropsychiatric presentation as the initial symptom. Thirty-seven patients (29.4%) had cardiac manifestations. Of these patients, nine presented apparent cardiac symptoms (three with discontinuous chest tightness, three with dizziness, two with palpitation and one with atypical chest pain) and 28 had asymptomatic electrocardiography (ECG) abnormalities. Among the nine patients, four had second- or third-degree atrioventricular block, three had ST-segment change and two had ventricular tachycardia. ECG abnormalities in the 28 patients included increase in the width of the QRS complex in 8, atrial premature beats in 8, T-wave inversion in 5, P-wave inversion in 2, sinus bradycardia in 2, ST-segment change in 2, and coexistence of sinus bradycardia and T-wave inversion in 1. No statistical difference (P = 0.32) existed in the occurrence of ECG abnormalities between patients with hepatic presentation (27/99) and those with neuropsychiatric presentation (10/27). CONCLUSION Cardiac involvement is not rare in adult WD patients. We suggest that cardiac evaluation should be routinely performed in the population.

Abstract
Wilson disease (WD) is a rare genetic condition that results from a build-up of copper in the body. It requires life-long treatment and is mainly characterized by hepatic and neurological features. Copper accumulation has been reported to be related to the occurrence of heart disease, although little is known regarding this association. We have conducted a systematic review of the literature to document the association between WD and cardiac involvement. Thirty-two articles were retained. We also described three cases of sudden death. Cardiac manifestations in WD include cardiomyopathy (mainly left ventricular (LV) remodeling, hypertrophy, and LV diastolic dysfunction, and less frequently LV systolic dysfunction), increased levels of troponin, and/or brain natriuretic peptide, electrocardiogram (ECG) abnormalities, and rhythm or conduction abnormalities, which can be life-threatening. Dysautonomia has also been reported. The mechanism of cardiac damage in WD has not been elucidated. It may be the result of copper accumulation in the heart, and/or it could be due to a toxic effect of copper, resulting in the release of free oxygen radicals. Patients with signs and/or symptoms of cardiac involvement or who have cardiovascular risk factors should be examined by a cardiologist in addition to being assessed by their interdisciplinary treating team. Furthermore, ECG, cardiac biomarkers, echocardiography, and 24-hours or more of Holter monitoring at the diagnosis and/or during the follow-up of patients with WD need to be evaluated. Cardiac magnetic resonance imaging, although not always available, could also be a useful diagnostic tool, allowing assessment of the risk of ventricular arrhythmias and further guidance of the cardiac workup.

Abstract
PURPOSE Although the hepatic and neurological consequences of Wilson's disease (WD) have been investigated in detail, its cardiac involvement remains little studied. Our aim was to investigate potential cardiac differences in strain (ST) and strain rate (STR) echocardiography in adult WD patients compared with controls. METHODS We included 30 patients with WD and a control group of 26 sex and age matched healthy adults. None of the subjects in either group had cardiac complaint. WD patients were clinically evaluated by a neurologist and undergone cranial magnetic resonance imaging. They were then divided into two groups according to the presence (NW) or absence (non-NW) of neurological involvement. Standard and advanced speckle tracking echocardiographic evaluations were performed in each group according to guidelines. RESULTS Left ventricular (LV) systolic and diastolic diameters and wall thickness measurements were within normal limits and did not differ significantly between the groups (P > .05). Neither atrial peak longitudinal and circumferential ST variables nor LV global and longitudinal ST and STR variables showed significant differences between the NW, the non-NW, and the control group (P > .05). CONCLUSION Our echocardiographic study showed no detectable difference between adult WD patients with or without neurological involvement and healthy subjects.

Abstract
BACKGROUND This study evaluated cardiac function using tissue Doppler echocardiography and assessed electrocardiographic findings in children diagnosed with Wilson's disease. METHOD Asymptomatic patients with a diagnosis of Wilson's disease (n = 43) were compared to healthy controls (n = 37) that were age and gender matched. RESULTS The standard electrocardiographic and conventional echocardiographic examinations were similar in both groups. The left ventricular ejection fraction, shortening fraction, and diastolic function were not significantly different between the two groups. The Tei index for mitral lateral, mitral septal, tricuspid lateral, tricuspid septal, and inter-ventricular septum on tissue Doppler echocardiography was higher in the patient group, yet it did not reach statistical significance. Mitral lateral and septal systolic annular velocity values were significantly lower in the patient group when compared to the control group (p = 0.02 and 0.04, respectively). Also, mitral lateral and septal isovolumetric contraction time values were higher in the patient group (p = 0.04). Although the left ventricular values were not significantly different, relative left ventricular wall thickness was higher in the patient group when compared to the control group, and concentric remodelling in the left ventricle was found in 7 (16%) of 42 patients. QT interval (p = 0.02) and P-wave dispersion values (p = 0.04) were significantly higher in the patient group compared to the control group, and these tend to predict arrhythmias. CONCLUSION Our study based on the tissue Doppler echocardiography assessment indicated a subclinical systolic, rather than diastolic, dysfunction in the myocardium with increased QT interval and P-wave dispersion, despite the young age of the patients and short disease duration.

Abstract
INTRODUCTION Wilson's disease (WD) is a rare genetic disorder that leads to impairments in copper metabolism. Patients principally exhibit liver and neuropsychiatric symptoms, but because copper also accumulates in all body organs, other (typically milder) clinical symptoms can occur. To date, cardiac involvement has not been thoroughly investigated in patients with WD. This study aimed to evaluate heart structure and function in patients with WD with commonly available diagnostic methods. MATERIAL AND METHODS We compared 125 WD patients with an age- and sex-matched control group. Patients with WD were grouped according to their dominant symptoms - neurologic or hepatic. All subjects underwent clinical, electrocardiographic (ECG), and echocardiographic examinations. RESULTS All subjects had sinus rhythm on electrocardiography. The only ECG parameter that differed between patients with WD and the control group was the QRS prolongation (92.0 vs. 86.4 ms; p < 0.05). On echocardiography patients with WD exhibited more hypertrophy in the left ventricle than controls (posterior wall in diastole: 1.0 vs. 0.93; p < 0.01) and the left ventricle hypertrophy was more pronounced in the neurologic than in the hepatic subgroup (1.05 vs. 0.96 cm; p < 0.01). Left ventricular systolic function was similar in the WD and the control group (ejection fraction: 67.5% vs. 67.7%). On tissue Doppler echocardiography patients with WD demonstrated slowing of myocardial relaxation, which was more evident in the neurologic group. CONCLUSIONS Heart involvement in WD was manifested mainly by mild left ventricular hypertrophy and subclinical changes in diastolic function, particularly in the patients with the neurologic form of disease.

Cardiac and autonomic function in patients with Wilson's disease. Orphanet J Rare Dis 2019; 14:22.

Abstract
Background The clinical effect of copper accumulation on the heart of patients suffering from Wilson’s disease (WD) is not completely understood. We aimed to determine if patients with WD show signs of cardiac involvement, structural heart disease or autonomic dysfunction. In this prospective trial, we studied 61 patients (mean age 44.3 ± 15.2 years, 51% males) with WD and compared them to 61 age- and gender-matched healthy controls. All subjects underwent clinical examination, blood tests, echocardiography and 24 h electrocardiographic (ECG) recording. Results Left- and right ventricular systolic function did not differ significantly between WD patients and controls. However, 5 of the 61 patients had a reduced left ventricular ejection fraction (LVEF). Furthermore, diastolic dysfunction was more prevalent in WD patients (9 of 61 vs. 0 of 61, p = 0.001). The severity of WD based on the Unified Wilson’s Disease Rating Scale was significantly correlated to NT-pro BNP (r = 0.34, P = 0.013). Patients with an exacerbation of WD in medical history had higher troponin levels compared to those without (11.3 ± 4.7 vs 4.6 ± 1.2). The autonomic function assessed by triangular index (TI) and SDNN-index was significantly reduced in WD patients compared to controls in most in almost every age category (p-value TI and SDNN: age 20–29, p < 0.001 and 0.05; age 30–39, p < 0.01 and not significant (ns); age 40–49, p < 0,01 and 0.001; age 50–59, p = ns and < 0.001, age 60–70, p < 0.05 and ns). Conclusion Our data demonstrate that cardiac involvement and autonomic dysfunction in WD is possible, however the underlying cause is still not known. We suggest that patients with signs and symptoms of structural heart disease should be examined by a cardiologist in addition to the interdisciplinary treatment team of WD.

Abstract
Background Neurologic and liver involvement in Wilson's disease (WD) is well-documented, however, few reports demonstrated cardiac involvement. Tpe and Tpe/QT are new measures of ventricular repolarization which were recently suggested as predictor of arrythmogenesis. We aimed to evaluate ventricular depolarization and repolarization parameters including QT, QTc, Tpe intervals, Tpe/QT, Tpe/QTc ratios, and QT dispersion (QTd) in patients with WD. Materials and methods Thirty-five patients with WD and 30 healthy controls were included in the study. Patients were evaluated by a neurologist in addition to MR imaging. Twenty-one of 35 patients were diagnosed as neuroWilson (NW), whereas 14 patients as non-NW. ECG recordings were obtained using a 12-lead commercial device (Cardiac Science, Burdick s500,USA). All patients underwent standard echocardiographic evaluation. These two groups of patients and healthy controls were compared. Results There were no difference between patients with WD and healthy controls in terms of age sex, BMI, liver, and kidney functions where as patients with WD were anemic and thrombocytopenic. Left atrial, ventricular dimensions, left ventricular systolic, and diastolic functions were similar between patients and healthy control. QT interval was prolonged in patient group, however, QTc, Tpe intervals, Tpe/QT, and Tpe/QTc ratios and QTd did not differ between groups. When patients with NW and non-NW were compared, both QT and QTc intervals were significantly longer in patients with NW, however, Tpe interval, Tpe/QT and Tpe/QTc ratios, and QTd did not differ. Conclusion QT and QTc intervals are prolonged in patients with Wilson's disease and neurologic involvement.

Abstract
Wilson's disease is a well-characterized disorder known to cause liver and brain disease due to abnormal copper deposition. Data regarding copper infiltration of the heart is conflicting, and the risk of heart disease has not been well described. We aimed to determine whether Wilson's disease is associated with cardiac myopathy, clinically evident in the atria as atrial fibrillation (AF) and in the ventricles as heart failure (HF). We longitudinally assessed 14.3 million patients in the California Healthcare Cost and Utilization Project database from 2005 through 2009 for diagnoses of Wilson's disease, AF, HF, and covariates using International Classification of Diseases-9th Edition codes. Cirrhosis and appendicitis diagnoses were assessed for positive and negative validation, respectively. We identified 463 patients with Wilson's disease. As expected in validation analyses, patients with Wilson's disease had a threefold greater risk of cirrhosis (hazard ratio [HR] 2.85, 95% confidence interval [CI] 2.81 to 2.90, p <0.0001) and no increased risk of appendicitis (HR 0.24, 95% CI 0.04 to 1.71, p = 0.16). Patients with Wilson's disease exhibited a 29% higher risk of AF after adjusting for age, gender, race, income, hypertension, diabetes, renal disease, hyperlipidemia, obesity, coronary disease, and obstructive sleep apnea (HR 1.29, 95% CI 1.15 to 1.45, p <0.0001). After adjusting for the same covariates, patients with Wilson's disease had a 55% higher risk of incident HF (HR 1.55, 95% CI 1.41 to 1.71, p <0.0001). Patients with Wilson's disease have an increased risk of AF and HF, supporting the need for careful surveillance for heart disease. These findings also suggest that the role of copper metabolism in heart disease should be more broadly investigated.

Abstract
Atrial fibrillation (AF) itself creates structural and electrophysiological changes such as atrial enlargement, shortening of refractory period and decrease in conduction velocity, called "atrial remodeling", promoting its persistence. Although the remodeling process is considered to be reversible, it has not been elucidated in detail. The aim of this study was to assess the feasibility of P wave dispersion in the assessment of reverse atrial remodeling following catheter ablation of AF. Consecutive 126 patients (88 males, age 63.0 ± 10.4 years) who underwent catheter ablation for paroxysmal AF were investigated. P wave dispersion was calculated from the 12 lead ECG before, 1 day, 1 month, 3 months and 6 months after the procedure. Left atrial diameter (LAD), left atrial volume index (LAVI), left ventricular ejection fraction (LVEF), transmitral flow velocity waveform (E/A), and tissue Doppler (E/e') on echocardiography, plasma B-type natriuretic peptide (BNP) concentrations, serum creatinine, and estimated glomerular filtration rate (eGFR) were also measured. Of all patients, 103 subjects remained free of AF for 1 year follow-up. In these patients, P wave dispersion was not changed 1 day and 1 month after the procedure. However, it was significantly decreased at 3 and 6 months (50.1 ± 14.8 to 45.4 ± 14.4 ms, p < 0.05, 45.2 ± 9.9 ms, p < 0.05, respectively). Plasma BNP concentrations, LAD and LAVI were decreased (81.1 ± 103.8 to 44.8 ± 38.3 pg/mL, p < 0.05, 38.2 ± 5.7 to 35.9 ± 5.6 mm, p < 0.05, 33.3 ± 14.2 to 29.3 ± 12.3 mL/m2, p < 0.05) at 6 months after the procedure. There were no significant changes in LVEF, E/A, E/e', serum creatinine, and eGFR during the follow up period. P wave dispersion was decreased at 3 and 6 months after catheter ablation in patients without recurrence of AF. P wave dispersion is useful for assessment of reverse remodeling after catheter ablation of AF.

Abstract
Wilson disease (WD) is a rare disorder of copper metabolism that presents mainly with hepatic and neuropsychiatric features. Copper accumulates not only in the liver and brain, but also in other organs. Liver injury can also be the cause of secondary impairment of other tissues. Therefore, the clinical manifestation of WD may be renal, cardiac, skin, osteoarticular, or endocrinologic and include other organ disturbances. Renal abnormalities include tubular dysfunction (e.g., renal tubular acidosis, aminoaciduria) and nephrolithiasis. Bone demineralization is a common manifestation in patients with WD. Cardiac injury may include arrhythmia, cardiomyopathy, and autonomic dysfunction. Different endocrine system manifestations, such as infertility or repeated miscarriages, growth and puberty disturbances, and hypoparathyroidism, are observed. Other important clinical aspects of WD include pancreas involvement, immunologic abnormalities, the presence of lipomas, and skin changes. Although other organ involvement is not common in WD and usually not severe, delayed diagnosis may lead to irreversible changes in organs and tissues. Therefore, awareness of other possible WD presentations is important in the differential diagnosis of WD.

Abstract
OBJECTIVE This study aimed to evaluate strain and strain rate echocardiography in children with Wilson's disease to detect early cardiac dysfunction. METHODS In this study, 21 patients with Wilson's disease and a control group of 20 age- and gender-matched healthy children were included. All the patients and the control group were evaluated with two-dimensional (2D) and colour-coded conventional transthoracic echocardiography by the same paediatric cardiologist using the same echocardiography machine (Vivid E9, GE Healthcare, Norway) in standard precordial positions, according to the American Society of Echocardiography recommendations. 2D strain and strain rate echocardiography were performed after the ECG probes of the echocardiography machine were adjusted for ECG monitoring. Longitudinal, transverse and radial strain, and strain rate were assessed from six basal and six mid-ventricular segments of the left ventricle, as recommended by the American Society of Echocardiography. RESULTS Left ventricular wall thickness, systolic and diastolic diameters, left ventricular diameters normalised to body surface area, end-systolic and end-diastolic volumes, cardiac output and cardiac index values were within normal limits and statistically similar in the patient and control groups (p > 0.05). Global strain and strain rate: the patient group had a statistically significant lower peak A longitudinal velocity of the left basal point and peak E longitudinal velocity of the left basal (VAbasR) point, and higher global peak A longitudinal/circumferential strain rate (GSRa) compared to the corresponding values of the control group (p < 0.05). Radial strain and strain rate: end-systolic rotation [ROT (ES)] was statistically significantly lower in the patient group (p < 0.05). Longitudinal strain and strain rate: end-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05). Segmental analysis showed that rotational strain measurement of the anterior and lateral segments of the patient group were statistically significantly lower than the corresponding values of the control group (p < 0.05). Segmental analysis showed statistically significantly lower values of endsystolic longitudinal strain [STSR (ES)] of the basal lateral (p < 0.05) and end-systolic longitudinal strain [SLSC (ES)] of the basal septal segment (p < 0.05) in the patient group. End-systolic longitudinal strain [SLSC (ES)] and positive peak transverse strain (STSR peak P) were statistically significantly lower in the patient group (p < 0.05). Segmental analysis showed statistically significantly lower values of endsystolic longitudinal strain [SLSC (ES)] of the mid-anterior and basal anterior segments (p < 0.05), end-systolic longitudinal strain [STSR (ES)] measurements of the posterior and mid-posterior segments, end-systolic longitudinal displacement [DLDC (ES)] of the basal posterior, mid-posterior and mid-antero-septal segments in the patient group. CONCLUSION Cardiac arrhythmias, cardiomyopathy and sudden cardiac death are rare complications but may be seen in children with Wilson's disease due to copper accumulation in the heart tissue. Strain and strain rate echocardiography is a relatively new and useful echocardiographic technique to evaluate cardiac function and cardiac deformation abnormalities. Our study showed that despite normal systolic function, patients with Wilson's disease showed diastolic dysfunction and regional deformation abnormalities, especially rotational strain and strain rate abnormalities.

Abstract
BACKGROUND Paroxysmal supraventricular arrhythmias (SVAs) frequently occur in patients with atrial septal aneurysm (ASA). The aim of the current study was to evaluate the electrocardiographic (P-wave duration and dispersion) and echocardiographic (atrial electromechanical delay, AEMD) noninvasive indicators of atrial conduction heterogeneity in healthy ASA subjects without interatrial shunt and to assess the AEMD role in predicting the SVAs onset in this population. MATERIALS AND METHODS One hundered ASA patients (41 males, mean age of 32.5 ± 8 years) and 100 healthy subjects used as controls, matched for age and gender, were studied for the occurrence of SVAs during a 4-year follow-up, through 30-day external loop recorder (ELR) monitoring performed every 3 months. ASAs were diagnosed by transthoracic echocardiography based on the criteria of a minimal aneurismal base of ≥15 mm and an excursion of ≥10 mm. Intra-AEMD and inter-AEMD of both atria were measured through tissue Doppler echocardiography. P-wave dispersion (PD) was carefully measured using 12-lead electrocardiogram (ECG). RESULTS Compared to the healthy control group, the ASA group showed a statistically significant increase in inter-AEMD, intra-left AEMD, maximum P-wave duration, and PD. Dividing the ASA group into 2 subgroups (patients with or without SVAs), the inter-AEMD, intra-left AEMD, P max, and PD were significantly higher in the subgroup with SVAs compared to the subgroup without SVAs. There were significant good correlations of intra-left AEMD and inter-AEMD with PD. A cutoff value of 40.1 msec for intra-left AEMD had a sensitivity of 82% and a specificity of 83% in identifying ASA patients at risk for SVA. CONCLUSION Our results showed that the echocardiographic AEMD indices (intra-left and inter-AEMD) and the PD were significantly increased in healthy ASA subjects without interatrial shunt. PD and AEMD represent noninvasive, inexpensive, useful, and simple parameters to assess the SVAs' risk in ASA patients.

Abstract
BACKGROUND Paroxysmal atrial tachyarrhythmias frequently occur in beta-thalassemia major (β-TM) patients.The aim of our study was to investigate the role of maximum P-wave duration (P max) and dispersion (PD), calculated trough a new manually performed measurement with the use of computer software from all 12-ECG-leads,as predictors of atrial-fibrillation (AF) in β-TM patients with conserved systolic or diastolic cardiac function during a twelve-months follow-up. MATERIALS AND METHODS 50 β-TM-patients (age38.4±10.1; 38M) and 50-healthy subjects used as controls, matched for age and gender, were studied for the occurrence of atrial arrhythmias during a 1-year follow-up, through ECG-Holter-monitoring performed every three months. The β-TM-patients were divided into two groups according to number and complexity of premature-supraventricular-complexes at the Holter-Monitoring (Group1: <30/h and no repetitive forms, n:35; Group2: >30/h or couplets, or run of supraventricular tachycardia and AF, n:15). RESULTS Compared to the healthy control-group, β-TM patients presented increased P-max (107.5± 21.2 vs 92.1±11ms, P=0.03) and PD-values (41.2±13 vs 25.1±5 ms,P=0.03). In the β-TM population, the Group2 showed a statistically significant increase in PD (42.8±8.6 vs 33.2±6.5ms, P<0.001) and P-max (118.1±8.7 vs 103.1±7.5ms, P<0.001) compared to the Group1. Seven β-TM patients who showed paroxysmal AF during this study had significantly increased P-max and PD than the other patients of the Group2. Moreover, P-max (OR:2.01; CI:1.12-3.59; P=0.01) and PD (OR=2.06;CI:1.17-3.64;P=0.01) demonstrated a statistically significant association with the occurrence of paroxysmal AF,P min was not associated with AF-risk (OR=0.99; CI:0.25-3.40; P=0.9) in β-TM-patients. A cut-off value of 111ms for P-max had a sensitivity of 80% and a specificity of 87%, a cut-off value of 35.5ms for PD had a sensitivity of 90% and a specificity of 85% in identifying β-TM patients at risk for AF. CONCLUSION Our results indicate that P-max and PD are useful electrocardiographic markers for identifying the β-TM-high-risk patients for AF onset, even when the cardiac function is conserved.

Abstract
Wilson's disease (WD) is a human disorder of copper homeostasis caused by mutations in the copper-transporting ATPase ATP7B. WD is characterized by copper accumulation, predominantly in the liver and brain, hepatic pathology, and wide differences between patients in the age of onset and the spectrum of symptoms. Several factors contribute to the phenotypic variability of WD. The WD-causing mutations produce a wide range of changes in stability, activity, intracellular localization, and trafficking of ATP7B; the nonpathogenic genetic polymorphisms may contribute to the phenotype. In Atp7b(-/-) mice, a mouse model of WD, an abnormal intracellular distribution of copper in the liver triggers distinct changes in the transcriptome; these mRNA profiles might be used to more specifically define disease progression. The major effect of accumulating copper on lipid metabolism and especially cholesterol homeostasis in mice and humans suggests the importance of fat and cholesterol metabolism as modifying factors in WD.

Abstract
OBJECTIVES Inflammatory diseases and inflammatory markers secreted by the liver, including C-reactive protein (CRP) and ceruloplasmin, have been associated with incident atrial fibrillation (AF). Genetic studies have not supported a causal relationship between CRP and AF, but the relationship between ceruloplasmin and AF has not been studied. The purpose of this Mendelian randomization study was to explore whether genetic polymorphisms in the gene encoding ceruloplasmin are associated with elevated ceruloplasmin levels, and whether such genetic polymorphisms are also associated with the incidence of AF. DESIGN Genetic polymorphisms in the ceruloplasmin gene (CP) were genotyped in a population-based cohort study of men from southern Sweden (Malmö Preventive Project; n = 3900). Genetic polymorphisms associated with plasma ceruloplasmin concentration were also investigated for association with incident AF (n = 520) during a mean follow-up of 29 years in the same cohort. Findings were replicated in an independent case-control sample (The Malmö AF cohort; n = 2247 cases, 2208 controls). RESULTS A single nucleotide polymorphism (rs11708215, minor allele frequency 0.12) located in the CP gene promoter was strongly associated with increased levels of plasma ceruloplasmin (P = 9 × 10(-10) ) and with AF in both the discovery cohort [hazard ratio 1.24 per risk allele, 95% confidence interval (CI) 1.06-1.44, P = 0.006] and the replication cohort (odds ratio 1.13, 95% CI 1.02-1.26, P = 0.02). CONCLUSIONS Our findings indicate a causal role of ceruloplasmin in AF pathophysiology and suggest that ceruloplasmin might be a mediator in a specific inflammatory pathway that causally links inflammatory diseases and incidence of AF.

Abstract
BACKGROUND P-wave dispersion (Pd) is an appealing marker for predicting the risk of developing atrial fibrillation. At present, no definitive cutoff value has been determined as to the diagnosis of high-risk patients. Our aims were to evaluate P-wave parameters of healthy subjects published in the literature, determine normal range and weighted means of Pd and P-wave parameters, and investigate the influences of gender, age, and BMI on the weighted results. METHODS A systematic search of studies published in PubMed was conducted. Only studies which included control groups of healthy individuals were included. RESULTS Of the 657 studies initially identified, 80 were eligible for inclusion. The total number of participants was 6,827. The highest reported Pd values were 58.56 ± 16.24 ms; the lowest were 7 ± 2.7 ms. The weighted mean was 33.46 ± 9.65 ms; weighted median was 32.2 ms. Gender and age were not found to be associated with significant influences on P-wave parameter values. High-normal BMI was not found to be associated with increased P-wave parameter values. CONCLUSIONS Pd, Pmax, and Pmin span a wide range of values in healthy individuals. Seemingly, abnormal values were often reported in healthy adults. The high variability of P-wave parameters in healthy individuals, and overlapping of the results with those reported for patients with increased risk for atrial fibrillation, might suggest that this technique has limited sensitivity and specificity. The variability between studies may stem from methodological issues and, therefore, there is a definite need for methodological standardization of Pd measurements.

Abstract
Although previous studies have documented a variety of electrocardiogram abnormalities in beta-thalassemia major (β-TM), little is known about P-wave dispersion (PD), an independent risk factor for development of atrial fibrillation. The aim of our study was to evaluate PD in β-TM patients with conserved systolic and diastolic functions. The study involved 40 β-TM patients (age 37.5 ± 10.2; 33 M) and 40 healthy subjects used as controls, matched for age and gender. PD was carefully measured using a 12-lead electrocardiogram. Cardiac iron levels were measured by cardiac magnetic resonance T2 star (CMR T2*) imaging. Comparing to the healthy control group, β-TM group presented increased values of the PD (40.1 ± 12.9 vs. 24 ± 7 ms; P < 0.004) and decreased CMR T2* imaging (29 ± 15 vs. 55 ± 13 ms; P = 0.03). We found a significant correlation between PD and CMR T2* values. Our study showed a significant increase of PD in β-TM patients with conserved systolic and diastolic cardiac functions. Our results indicate that PD is correlated to myocardial iron deposit, as assessed by CMR T2* imaging.
