一、概述心脏起搏器电极的作用,是把起搏器和心脏联结起来,将起搏器产生的刺激电流,转换成心肌内的离子流,由此对心脏实施起搏功能。对于具有感知功能的起搏器来说,电极还可以将心电活动的心肌离子流转换成起搏器的输入信号,由此达到感知的目的。电极是起搏器的组成部分。人们往往把联 First, an overview Pacemaker electrode role is to connect the pacemaker and the heart, the pacemaker stimulus current, into the myocardial flow of ions, which pacing the implementation of the heart function. For pacemakers with sensing capabilities, the electrodes can also convert the electrocardiogramically-active myocardial ion flow into pacemaker input signals for sensing purposes. The electrode is an integral part of the pacemaker. People tend to couple
