["Digitalis" arrhythmias and their treatment].

The observation was conducted in 92 patients with rhythm and conductivity disorders induced by cardiac glycosides. Most of the patients had ischaemic heart disease, 60 of them having had acute myocardial infarction. All patients were prescribed cardiac glycosides (usually Strophantin and digitalis preparations) due to the appearance of cardiac insufficiency. The most frequently observed rhythm disorder consisted in ventricular extrasystole (69.5% of the cases), bigeminy, polytopic or group extrasystole being observed in many cases. Often arrhythmias consisted in atrial extrasystole, atrial fibrillation, atrial and ventricular tachycardia, atrioventricular block. "Digitalis" arrhythmias were treated with beta-adrenergic blockers: Inderal, Viskene, Eraldin, Trasicor and Aptin. These drugs proved effective in most cases with atrial arrhythmias and in some--with ventricular arrhythmias. Lidocain was more effective in cases of ventricular arrhythmias. Effective drugs of a broad spectrum are also Aimalin, Pulsenorma and Ritmodan.
