Abstract
To evaluate the significance of clinical, hemodynamic and electrocardiographic risk factors in idiopathic dilated cardiomyopathy 94 patients were followed prospectively for 49 +/- 37 months. During follow-up, 30 patients died, 13 died suddenly, 13 died of congestive heart failure and 4 of other causes. Follow-up was completed in 85 patients, and overall cardiac mortality was 31%. Univariate analysis revealed left ventricular ejection fraction among 20 variables as the major indicator of risk of both cardiac death of all causes and sudden cardiac death separately. Multivariate overall analysis determined 3 independent risk factors in the following order for all causes of cardiac death: Ventricular pairs > 40/24 hours (RR 7.2, p < 0.0001), left ventricular ejection fraction < or = 35% (RR 6.5, p < 0.001) and first- or second-degree atrioventricular (AV) block (RR 3.1, p < 0.05). In the subset of patients with ejection fraction < or = 35% ventricular pairs > 40 per 24 hours (RR 10.7, p < 0.001), AV block (RR 3.9, p < 0.05), and the missing administration of vasodilators (RR 3.3, p < 0.05) were the most important. The chief risk factors for sudden cardiac death were age (RR 7.4, p < 0.01) and AV block (RR 4.6, p < 0.05) by adjustment for age, and ejection fraction < or = 35% (RR 7.1, p < 0.01) and AV block (RR 4.2, p < 0.05) if not adjusted for age. A differentiation into 4 risk groups was attempted. The additional independent prognostic importance of AV block was shown, especially in combination with reduced ejection fraction or a high incidence of ventricular pairs.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To clarify the clinical and prognostic value of the ECG, an ECG review was undertaken in 45 consecutive patients with a histologic diagnosis of active myocarditis (29 men and boys and 16 women and girls; age, 36.8 +/- 15 years; idiopathic myocarditis, 39 cases). In patients (21) with symptoms of recent onset (less than or equal to 1 month) AV block and repolarization abnormalities were the prevailing ECG features at the time of admission, and a pseudoinfarction pattern (Q waves plus ST-segment elevation) frequently heralded a rapidly fatal course ("fulminant myocarditis"). Left atrial enlargement and atrial fibrillation, left ventricular hypertrophy and LBBB, which prevailed in patients who had symptoms for longer periods, corresponded to the most severe degree of left ventricular dysfunction during the initial hemodynamic and echocardiographic evaluation. The overall mortality rate after 58 +/- 24 months from the time of diagnosis was 29%. Abnormal QRS complexes and LBBB were markers of poor survival, independently of initial indexes of left and right ventricular function, both of which indicate an increased propensity for sudden cardiac death.

Abstract
Three patients with primary congestive cardiomyopathy (COCM), complete left bundle branch block (LBBB) and right axis deviation in the standard leads are described. Review of 50 additional patients from the literature since 1950 indicates that the uncommon combination of LBBB and RAD is a marker of severe myocardial disease, especially COCM. The mechanism of production of this electrocardiographic pattern appears to be diffuse conduction system involvement in advanced myocardial disease.
