摘　　要：４７例并行性室性心动过速中，３５例见于正常心脏（占７４．５％），发病常由过度疲劳、精神紧张诱发，易被利多卡因、普罗帕酮控制，２９例随访结果预后良好。Forty seven cases of parasystolic ventricular tachycardia were reported, among them 5 cases of coronary heart disease, 2 of hypertensive cardiopathy,1 of dilated cardiomyopathy,4 of viral myocarditis, 35 without organic heart disease.The last category amounted to 74.5% of the total cases,and most of them were young or middle-aged with inducing factors such as overwork, mental stress, insomnia, etc. The frequencies of parasystolic ventricular tachycardia averaged 96.8±18.2 beats per minute, and the persistent time was not long with an average of 24.3±15.6 seconds. Most of the QRS shape was single with no severe hemodynamic changes and mild clinical symptoms. It might be regarded as benign ventricular tachycardia. Parasystolic ventricular tachycardia either stops automatically, or can be easily controlled with lidocaine, mexiletine and propafenone. It is not necessary to treat cases of asymptomatic parasystolic ventricular tachycardia. Follow-up survey of 29 cases showed favourable prognosis.
