A total of 20 patients (16 males and 4 females) with repetitive nonparoxysmal ventricular tachycardia (RNVT) underwent Holter monitoring of ECG, bicycle exercise test, intracardiac electrophysiological measurements. The findings evidence for a principal difference of this tachycardia form from paroxysmal ventricular tachycardia by trigger mechanism. All the tests performed showed rhythm-dependence of RNVT, tachycardia cannot be initiated by electrocardiostimulation, but can be stopped after intravenous introduction of finoptin. It is evident that this form of cardiac arrhythmia is due to the mechanism of pathological ectopic automatism represented, most likely, by trigger activity, but not re-entry, as it is in the majority of patients with paroxysmal ventricular tachycardia.
共有20例（16例男性和4例女性）反复非阵发性室性心动过速（RNVT）患者接受了动态心电图监测、自行车运动试验及心内电生理测量。这些发现证明了这种心动过速形式在触发机制上与阵发性室性心动过速存在主要差异。所进行的所有检查均显示RNVT具有节律依赖性，心动过速不能通过电刺激诱发，但静脉注射心得安后可终止。显然，这种心律失常形式是由病理性异位自律机制引起的，很可能由触发活动而非折返引起，而大多数阵发性室性心动过速患者是由折返引起的。
