Abstract
Paroxysmal supraventricular tachycardia (PSVT) is a common arrhythmia in adults. Its occurrence depends on the presence of the reentry circuit and the trigger of the paroxysm. Stress, emotional factors, and comorbidities favour the occurrence of such an episode. We hypothesized that the occurrence of PSVT follows extreme thermal episodes. The retrospective analysis was based on the data collected from three hospital emergency departments in Poland (Olsztyn, Radom, and Wroclaw) involving 816 admissions for PSVT in the period of 2016-2021. To test the hypothesis, we applied the Universal Climate Thermal Index (UTCI) to objectively determine exposure to cold or heat stress. The risk (RR) for PSVT increased to 1.37 (p = 0.006) in cold stress and 1.24 (p = 0.05) in heat stress when compared to thermoneutral conditions. The likelihood of PSVT during cold/heat stress is higher in women (RR = 1.59, p< 0.001 and RR = 1.36, p = 0.024, respectively) than in men (RR = 0.64 at p = 0.088 and RR = 0.78, p = 0.083, respectively). The susceptibility for PSVT was even higher in all groups of women after exclusion of perimenopausal group of women, in thermal stress (RR = 1.74, p< 0.001, RR = 1.56, p = 0.029, respectively). Females, particularly at the perimenopausal stage and men irrespective of age were less likely to develop PSVT under thermal stress as compared to thermoneutral conditions. Progress in climate change requires searching for universal methods and tools to monitor relationships between humans and climate. Our paper confirms that the UTCI is the universal tool describing the impact of thermal stress on the human body and its high usefulness in medical researches.

Abstract
Our aims were to assess, in healthy young females and males, the effects of the linear joint variation of respiratory frequency (RF) and tidal volume (VT) on the logarithmic transformation of high-frequency power of RR intervals (lnHF). ECG and VT were recorded from 18 females and 20 males during three visually guided 30-s breathing maneuvers: linearly increasing RF (RFLI) at constant VT; linearly increasing VT (VTLI) followed by decreasing VT (VTLD) at fixed RF, and RFLI and VTLI-VTLD combined. VT of females was 20% smaller. Instantaneous RF and lnHF were computed from the time-frequency distributions of respiratory series and RR intervals. LnHF-RF and lnHF-VT relations were similar between genders. LnHF and RR intervals control-maneuver differences during combined maneuver were approximately equal to the sum of those of the independent maneuvers. LnHF-RFLI relation showed strong negative correlations in separated and combined conditions, with steeper slope in the latter (p < 0.001). LnHF-VTLI and lnHF-VTLD relations presented, in the independent maneuvers, three combinations of slopes of different sign, all with hysteresis, and in the combined maneuver, strong correlations with negative slope for VTLI and positive slope for VTLD, steeper (p < 0.001) and with greater hysteresis (p < 0.001) than the independent ones. LnHF responses to our fast, non-fatiguing and non-steady-state breathing maneuvers are: similar between genders; consistent attenuation due to RFLI, whether applied alone or combined; ambiguous and with hysteresis to independent VTLI-VTLD variations; systematic greater attenuation during RFLI combined with VTLI-VTLD, equal to the sum of the independent effects, indicating that there is no interference between them.

Abstract
OBJECTIVE Low resting respiratory sinus arrhythmia (RSA) levels and blunted RSA reactivity are thought to index impaired emotion regulation capacity. Major depressive disorder (MDD) has been associated with aberrant RSA reactivity and recovery to a speech stressor task relative to healthy controls. Whether impaired RSA functioning reflects aspects of the depressed mood state or a stable vulnerability marker for depression is unknown. METHODS We compared resting RSA and RSA reactivity between adults with MDD (n = 49), remitted depression (RMD, n = 24), and healthy controls (n = 45). Electrocardiogram data were collected during a resting baseline, a paced-breathing baseline, and two reactivity tasks (speech stressor, cold exposure). RESULTS A group by time quadratic effect emerged (F(2,109) = 4.36, p = .015) for RSA across phases of the speech stressor (baseline, instruction, preparation, speech, recovery). Follow-up analyses revealed that those with MDD uniquely exhibited blunted RSA reactivity, whereas RMD and controls both exhibited the anticipated task-related vagal withdrawal and posttask recovery. The group by time interaction remained after covariation for age, sex, waist circumference, physical activity, and respiration, but not sleep quality. CONCLUSIONS These results provide new evidence that aberrant RSA reactivity marks features that track the depressed state, such as poor sleep, rather than a stable trait evident among asymptomatic persons.

A comparison of major depressive disorder remitted depression and healthy controls. Int J Psychophysiol 2013; 90:50-7. [PMID: 23756147 PMCID: PMC4386598 DOI: 10.1016/j.ijpsycho.2013.05.018] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2012] [Revised: 05/21/2013] [Accepted: 05/31/2013] [Indexed: 10/26/2022]
Abstract
Prior work has repeatedly demonstrated that people who have current major depression exhibit blunted cardiovascular reactivity to acute stressors (e.g., Salomon et al., 2009). A key question regards the psychobiological basis for these deficits, including whether such deficits are depressed mood-state dependent or whether these effects are trait-like and are observed outside of depression episodes in vulnerable individuals. To examine this issue, we assessed cardiovascular reactivity to a speech stressor task and a forehead cold pressor in 50 individuals with current major depressive disorder (MDD), 25 with remitted major depression (RMD), and 45 healthy controls. Heart rate (HR), blood pressure and impedance cardiography were assessed and analyses controlled for BMI and sex. Significant group effects were found for SBP, HR, and PEP for the speech preparation period and HR, CO, and PEP during the speech. For each of these parameters, only the MDD group exhibited attenuated reactivity as well as impaired SBP recovery. Reactivity and recovery in the RMD group more closely resembled the healthy controls. Speeches given by the MDD group were rated as less persuasive than the RMD or healthy controls' speeches. No significant differences were found for the cold pressor. Blunted cardiovascular reactivity and impaired recovery in current major depression may be mood-state dependent phenomena and may be more reflective of motivational deficits than deficits in the physiological integrity of the cardiovascular system.

Abstract
Mechanisms relating Type D personality to poor health are largely unknown, with autonomic nervous system function being a candidate. This study examined the physiologic response to cold stress. Undergraduates (N = 101, 84% female) underwent a cold pressor test. An electrocardiogram, impedance cardiogram, and blood pressure were recorded. Type D personality was assessed by self-report questionnaire. Type D was associated with increased systolic and diastolic blood pressure reactivity. Exploratory analyses showed Type D men to respond with increased respiratory sinus arrhythmia (i.e., higher parasympathetic activity), and decreased pre-ejection period (i.e., larger sympathetic activity), while Type D women showed a reciprocal response pattern. In conclusion, Type D personality was associated with an exaggerated hemodynamic response to cold stress, which may contribute to an increased risk of hypertension in Type D individuals.

Timing and gender determine if acute pain impairs working memory performance. THE JOURNAL OF PAIN 2013; 14:1320-9.

Abstract
UNLABELLED The effects of pain on memory are complex, and little is known about the vulnerability of working memory (WM) performance when individuals complete a WM test while concurrently experiencing pain. Here, we subjected 78 healthy nonsmoking participants to either acute pain or a control condition while we administered a WM test. In this context, we also tested WM 20 minutes after pain in order to determine if timing of pain affected WM performance, and assessed objective and subjective measures of pain. We hypothesized that pain would impair WM performance during pain. Further, women's WM performance would be impaired more than men. Importantly, there was an interaction between gender and condition, with women exposed to pain experiencing impairments during but not after the cold pressor task. Our data imply that timing and gender are critically important in whether acute pain is costly to WM performance. Our findings have interesting clinical, professional, and educational implications, and understanding the influence of pain could help to improve the interpretation of WM tests in these diverse settings. PERSPECTIVE Results of this study support the growing body of work that attests to the detrimental effect of pain on WM performance. Further, this study provides new evidence that concurrently experiencing cold pressor pain impairs WM in regularly menstruating women and women taking a contraceptive.

Abstract
Low vagal function is related to several disorders. One possible underlying mechanism linking the vagus nerve and disorders is the HPA axis. Thirty-three healthy male subjects participated in a stress task, while heart rate (HR), respiratory sinus arrhythmia (RSA), salivary cortisol, and mood were assessed. Vagal function was determined using baseline, stress-induced inhibition, and Cold Face Test (CFT)-induced stimulation. The stress task induced a significant increase in cortisol and HR, a decrease in RSA, and a worsening of mood. A linear regression model with the time from CFT onset until maximum bradycardia as the independent variable explained 17.9% of the total variance in cortisol in response to the stressor (mood: 36.5%). The results indicate that a faster CFT response is associated with reduced cortisol increase and enhanced mood after acute stress. Our data support an inverse relationship between vagal function and the HPA axis.

Abstract
OBJECTIVE To evaluate the impact of acute stress and relationship-focused imagery on cardiac vagal control, as indicated by levels of respiratory sinus arrhythmia (RSA), in depressed and nondepressed women. Impairment in cardiac parasympathetic (vagal) control may confer risk for cardiac mortality in depressed populations. METHODS Electrocardiogram and respiratory rate were evaluated in 15 nonmedicated depressed women and 15 matched controls during two laboratory conditions: 1) a relationship-focused imagery designed to elicit vagal activation; and 2) a speech stressor designed to evoke vagal withdrawal. RESULTS As expected, the relationship-focused imagery increased RSA (F(3,66) = 3.79, p = .02) and the speech stressor decreased RSA (F(3,66) = 4.36, p = .02) across women. Depressed women exhibited lower RSA during the relationship-focused imagery, and this effect remained after control for respiratory rate and trauma history (F(1,21) = 5.65, p = .027). Depressed women with a trauma history exhibited the lowest RSA during the stress condition (F(1,22) = 9.61, p = .05). However, after controlling for respiratory rate, Trauma History × Task Order (p = .02) but not Trauma History × Depression Group (p = .12) accounted for RSA variation during the stress condition. CONCLUSION Depression in women is associated with lower RSA, particularly when women reflect on a close love relationship, a context expected to elicit vagal activation and hence increase RSA. In contrast, depression-related variation in stressor-evoked vagal activity seems to covary with women's trauma history. Associations between vagal activity and depression are complex and should be considered in view of the experimental conditions under which vagal control is assessed, as well as physiological and behavioral factors that may affect vagal function.

Abstract
BACKGROUND Depression and anger/aggression-related traits are thought to promote coronary disease, at least in part, through their associations with stress-related cardiovascular processes. It is unclear whether the effects of these factors on cardiovascular reactivity (CVR) are redundant, additive, or synergistic. PURPOSE The main goal of this study was to examine the independent and interactive effects of depressive symptoms and anger/aggression-related traits in promoting CVR. METHODS Participants were 63 healthy females who completed the Beck Depression Inventory and Buss-Perry Aggression Questionnaire and performed a stressful speaking task. Systolic and diastolic blood pressure (SBP and DBP) and heart rate were recorded. RESULTS Significant interaction effects indicated that depressive symptoms were positively associated with SBP and DBP reactivity among women high in verbal aggression but not among those low in verbal aggression. CONCLUSIONS Depressive symptoms and verbal aggression may interact to promote exaggerated blood pressure responses to stressors, a possible marker for mechanisms that contribute to heart disease.

Abstract
OBJECTIVE Evidence suggests that emotional stress can trigger acute coronary syndromes in patients with advanced coronary artery disease (CAD), although the mechanisms involved remain unclear. Hostility is associated with heightened reactivity to stress in healthy individuals, and with an elevated risk of adverse cardiac events in CAD patients. This study set out to test whether hostile individuals with advanced CAD were also more stress responsive. METHODS Thirty-four men (aged 55.9+/-9.3 years) who had recently survived an acute coronary syndrome took part in laboratory testing. Trait hostility was assessed by the Cook Medley Hostility Scale, and cardiovascular activity, salivary cortisol, and plasma concentrations of interleukin-6 were assessed at baseline, during performance of two mental tasks, and during a 2-h recovery. RESULTS Participants with higher hostility scores had heightened systolic and diastolic blood pressure (BP) reactivity to tasks (both P<.05), as well as a more sustained increase in systolic BP at 2 h post-task (P=.024), independent of age, BMI, smoking status, medication, and baseline BP. Hostility was also associated with elevated plasma interleukin-6 (IL-6) levels at 75 min (P=.023) and 2 h (P=.016) poststress and was negatively correlated with salivary cortisol at 75 min (P=.034). CONCLUSION Hostile individuals with advanced cardiovascular disease may be particularly susceptible to stress-induced increases in sympathetic activity and inflammation. These mechanisms may contribute to an elevated risk of emotionally triggered cardiac events in such patients.

Abstract
OBJECTIVE To test whether reduction in hostility increases autonomic regulation of the heart. METHODS In this randomized controlled trial, participants were 158 healthy adults, aged 20 years to 45 years, who were 1 standard deviation (SD) above national norms on the Cook-Medley Hostility and the Spielberger Trait Anger Indices. Participants also were interviewed, using the Interpersonal Hostility Assessment Technique (IHAT). They were randomly assigned to a 12-week cognitive behavior therapy program for hostility reduction or a wait-list control condition. The main outcome measure was cardiac autonomic modulation, measured as RR interval variability (RRV) derived from 24-electrocardiographic recordings. RESULTS In a multivariate analysis of variance assessing psychological outcomes of hostility, anger, and IHAT scores, there was a significant treatment effect with an average reduction across the three outcomes that was approximately 0.7 SD (ES = 0.685, SE = 0.184, p < .001) greater for the intervention group than for the control group. In contrast, the change in heart rate was -0.14 beat/min (95% Confidence Interval [CI] = -2.43, 2.14) in treatment participants and -1.36 beat/min (95% CI = -3.28, 0.61) in wait-list participants. High-frequency RRV, an index of cardiac parasympathetic modulation, increased by 0.07 ln ms(2) (95% CI = -0.10, 0.24) for participants in the treatment condition and decreased by 0.04 ln ms(2) (95% CI = -0.18, 0.10) for participants in the wait-list condition. These differences were not significant. The findings for other indices of RRV were similar. CONCLUSIONS Reduction of hostility and anger was not accompanied by increases in cardiac autonomic modulation. These findings raise questions about the status of disordered autonomic nervous system regulation of the heart as a pathophysiological mechanism underlying the hostility-heart disease relationship and about whether hostility itself is a mechanism or merely a marker of elevated risk of heart disease.

Abstract
We examined relationships between three emotion-regulation constructs and autonomic physiology in metastatic breast cancer patients (N = 31). Autonomic measures are not often studied in breast cancer patients and may provide evidence of an increase in allostatic load. Patients included participated as part of a larger clinical trial of supportive-expressive group therapy. Systolic and diastolic blood pressure and heart rate were assessed at a semi-annual follow-up. We averaged 3 resting assessments and used measures of Repression, Suppression, Restraint of Hostility, and Body Mass Index as predictors of autonomic response. We found that higher repression was significantly associated with higher diastolic blood pressure, while higher restraint of hostility was significantly associated with higher systolic blood pressure. A repressive emotion regulation style may be a risk factor for higher sympathetic activation possibly increasing allostatic load, while restraint of hostility may be a protective factor for women with metastatic breast cancer.

Abstract
The autonomic characteristics of hostility and defensiveness were assessed in 55 male undergraduates based on composite Cook Medley Hostility (Chost) and Marlowe Crowne Social Desirability (MC) scores to create 4 groups: Defensive Hostile (DH; high MC, high Chost), High Hostile (HH; low MC, high Chost), Defensive (Def; high MC, low Chost) and Low Hostile (LH; low MC, low Chost). All subjects engaged in a video game (VG) and hand cold pressor (CP) task. Cardiovascular responses in DH subjects were predicted to show enhanced sympathetic alpha and beta-adrenergic activity and the least vagal control compared to others across tasks. DH and LH men showed significant heart rate reactivity to the CP task compared to HH men. LH men showed significant reductions in high frequency power (vagal assessment) to the tasks compared to HH men. Future studies may employ harassment techniques and include the factors of gender and ethnicity in their assessments.
