[Parasystolic arrhythmias]

The observation was conducted in 24 patients with parasystolic arrhythmias, 13 of them having parasystolic extrasystoles, and 11--paroxysmal and non-paroxysmal parasystolic tachycardia. Ventricular parasystole was found in 21 patients, atrial--in 3, atrioventricular--in 2; three patients had double parasystole with two ectopic centers. In the majority of patients their parasystole took a persistent, but relatively benign course, however one patient with ventricular parasystolic tachycardia persisting for many years had repeated ventricular fibrillations. For the treatment of supraventricular parasystolic arrhythmias beta-adrenergic receptors blocking agents, Isoptine, cardiac glycosides were used; in ventricular parasystole the more effective drugs are Lidocain, Novocainamid, Ajmalin.
