[Diagnostic value of diurnal ECG monitoring, the bicycle exercise test and intracardiac electrophysiological study in the detection of arrhythmia in patients with alcoholic lesions of the heart].

Altogether 53 patients with stage II chronic alcoholism were investigated to study the diagnostic significance of circadian ECG monitoring (CECGM), bicycle ergometry (BEM) and intracardiac electrophysiological investigation (EPI) in the detection of arrhythmias. The results obtained suggested that the most informative method of diagnosis of paroxysmal arrhythmias in patients with alcoholic cardiac lesions was EPI with which arrhythmical paroxysms were detected in 29.6%, whereas CECGM and BEM turned out diagnostically significant in 7.4%. Occult arrhythmical paroxysms were detected for the first time using EPI of the heart.
