[Nonischemic ventricular arrhythmias: classification, clinical manifestations, diagnosis, and treatment].

Clinico-electrocardiographical and electrophysiological features of noncoronarygenic ventricular arrhythmias are presented. Characteristics of localization of arrhythmogenic focus in various parts of left and right ventricular myocardium, in interventricular septum, and in immediate vicinity of each of 4 valves are discussed. Spectrum of necessary diagnostic measures is delineated, and assessment of efficacy of drug therapy is given.
