A patient initially had syncope due to a runaway pacemaker firing at an unusually rapid rate (30 impulses per second). The ventricular arrhythmia was characterized by numerous ectopic beats, with coupling intervals related to the length of the preceding cycle and runs of ventricular tachycardia with slight variations in the intervals between beats. This case demonstrates the clinical characteristics of a very rapidly firing, low-intensity, ventricular parasystolic focus.
一名患者最初因起搏器失控以异常快速的速率(每秒30次冲动)发放信号而出现晕厥。室性心律失常的特征是有大量异位搏动,联律间期与前一心动周期的长度相关,以及室性心动过速发作时搏动间期略有变化。该病例展示了一个发放信号非常快速、强度较低的室性并行心律起搏点的临床特征。
