反复心搏是一种以交界区为转折点的大折返(gross re-entry)现象。按起搏点不同,反复心搏可分为窦性、房性、交界性与室性四类。在反复心搏连续发生过程中,除始动心搏随起搏点不同而有所区别外,其后续部分不论起搏点在何处一般均为室上性QRS与逆P交替出现,直至发作中止。反复心搏与前一心搏的时距为反复时间(或配对时间),一般均较短(≤0.50秒)。作者遇到室早双联律引起伴室内差异传导的反复心搏一例,同时有交界性
Repeated heartbeat is a gross re-entry that takes the junction as a turning point. According to different pace of pacing, repeated heartbeat can be divided into sinus, atrial, borderline and ventricular four categories. In the continuous heartbeat process, in addition to starting heartbeat pace with different points vary, the follow-up part of the pacemaker regardless of where are generally supraventricular QRS and inverse P alternating until the seizure of stop . Repeated heartbeat and heartbeat time interval for the repeated time (or matching time), are generally shorter (≤ 0.50 seconds). The author encountered a double as early as the law caused by repeated ventricular conduction with the heart of a case of repeated, at the same time there are borderline
