经胸肌的临时心脏起搏方法的实验研究

目的：本文探讨一种新的体外临时心脏临时心脏起搏方法。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起搏电极，在它的背部靠近心脏的相关位置贴上一场阳性起搏电极；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

Experiment research of temporary cardiac pacing method through chest muscle

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 necdle-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.
