对于心律不齐,特别是心率在每分钟30次以下者,要向心脏施以电刺激,使心跳恢复到正常,这种刺激装置叫心脏起搏器,或者简称为起搏器。为了对心脏施行电刺激,要从静脉向心室插入附有电极的导管,使用约5V,1ms的脉冲刺激,这种最简单的,给以一定周期的脉冲刺激起搏器,叫固定速度起波器。通常当自发心率恢复正常时,为了不使心率与起搏
For arrhythmia, especially the heart rate at 30 times per minute or less, to the heart to impose electrical stimulation, so that returned to normal heartbeat, this device called the pacemaker cardiac pacemaker, or simply pacemaker. In order to perform electrical stimulation on the heart, a catheter with an electrode inserted into the ventricle from the vena cava should be pulsed with a pulse of about 5 V and 1 ms. This simplest pulse stimulating pacemaker with a certain period is called a fixed speed wave Device. Usually when spontaneous heart rate returns to normal, in order not to make heart rate and pacing
