[A comparative analysis of rhythm and conduction disorders in patients with dilated cardiomyopathy and chronic myocarditis].
Rhythm and conduction disturbances were compared for 20 patients with dilated cardiomyopathy (group 1) versus 20 patients with chronic myocarditis (group 2). The diagnosis was confirmed at coronary ventriculography and morphological examination of left and right ventricular endomyocardial biopsies. There were minor differences in the parameters studied I, though supraventricular arrhythmia varied more in group 2. The frequency of ventricular arrhythmia appeared higher in group 2 only in circulatory insufficiency stage 1-IIA. Quantitative differences in ventricular and supraventricular arrhythmias between the groups under moderate circulatory insufficiency may result from different morphological changes in the myocardium.
