大鼠实验性心肌缺血24小时动态心电图检测及分析

A dynamic electrocardiogram analysis in rats with 24hours of experimental myocardial ischemia

本文分析了大鼠实验性心肌缺血２４小时中动态心电图变化，提示室性心律失常较为常见，快速室性心律失常好发于缺血后１０～２０ｍｉｎ及２～３ｈ，而缓慢性心律失常（窦性静止、Ⅲ°ＡＶＢ）则多见于缺血后５～７ｈ。

dynamic electrocardiogram analysis in rats with 24h of experimental myocardial ischemia was made. The results showed that ventricular arrhythmias were more common than other types of arrhythmis. Ventricular tachyarrhythmias occurred chiefly in periods from 10min to 20min and from 2h to 3h after myocardial ischemiabut bradyarrhythmias(Ⅲ°AVB and sinus pauses )occurred chiefly in period from 5h to 7h after myocardial ischemia .
