摘　　要：目的 本文探讨一种新的体外临时心脏起搏方法。方法 本项研究利用作者自行研制的起搏方式、起搏频率、起搏脉宽和起搏电流均可调的微机化多功能体外临时心脏起搏装置发送起搏信号；在雄性杂交犬的心前区的胸肌插入一根针状阴性起搏电极，在它的背部靠近心脏的相关位置贴上一块阳性起搏电极；在实验雄性杂交犬的静脉注射异搏定5mg 5分钟后实验雄性杂交犬的自主心律突然停止；此时进行临时心脏起搏实验并观察起搏效果。结果 实验雄性杂交犬经本文介绍的临时心脏起搏后，恢复心跳，心电图纸上出现起搏心电图，起搏有效。结论 这是一种新的有应用前景的体外临时心脏起搏方法。Objective The paper inquires into a new external temporary cardiac pacing method． Method The research uses a microcomputer－based multi－functional external temporary cardiac－pacing device made by the authors for sending pacing signals． The pacing mode and pacing rate of the device can be adjustable． The pacing pulse width and pacing current of the device can also be adjustable． It inserts a syringe needle－like negative pacing pole into the chest muscle in the prior－cardiac area of a male adult mongrel dog it pastes a positive pacing pole on the back area near heart of the dog． It takes intravenous injection isoptin 5mg into the male mongrel dog． After 5 minutes the heartbeat of the dog suddenly stops it does pacing experiment for the dog at this time and observes the results of the pacing experiment． Results After temporary cardiac pacing the heartbeat of the dog returns pacing ECG of the dog appears the pacing for the dog is active． Conclusions It is a new and benefit external temporary cardiac pacing method．
