室性心动过速（VT）不同起始方式的临床和电生理特征已被广泛研究。研究中至少定义了两种不同的室性心动过速发作模式。心动过速，其之前是一个单一的或多个心室异位活动，包括一个短-长-短序列，被定义为非突然发作，而那些，之前没有心室异位被定义为突然发作。了解室性心动过速的起始模式可能具有一定的临床意义，并对治疗策略的选择至关重要。使用霍尔特心电图和分析植入式心律转复除颤器的心内心电图能够评价VT的起始模式。
Clinical and electrophysiological features of different initiation patterns of ventricular tachycardia (VT) have been widely studied. At least two different onset patterns of VT have been defined in the studies. Tachycardias, which are preceded by either a single or multiple ventricular ectopic activity, including a short–long–short sequence, are defined as nonsudden onset and those, which are not preceded by ventricular ectopy are defined as sudden onset. The knowledge of initiation pattern of VTs may have some clinical importance and can be essential for the selection of treatment strategies. The use of Holter electrocardiograms and analysis of intracardiac electrograms from implantable cardioverter–defibrillators enables to evaluate the initiation patterns of VTs.
