title: [Ventricular arrhythmias in reduced glycoside tolerance and digitalis poisoning together with myocardial infarct].
abstract: Electrophysiological fundamental principles of the heart muscle cell and the conduction system are discussed in detail. Basic differences are described. Pathophysiology of ventricular arrhythmias is emphasized, especially the ectopic conduction development and conduction defect of the reentry mechanism. Decreased digitalis tolerance of different causes and overdosage of digitalis may lead to ventricular premature heart beats and tachycardias. Myocardial infarction is discussed in detail because lethality within the first hours of infarction is mostly caused by ventricular fibrillation.
