电流对心脏能起兴奋作用的现象,人们知道很久,但一次电刺激能使心脏产生一次收缩,这种知识,直到近来才被应用于临床。心脏电起搏器治疗心律失常,是近年来心脏病治疗上的重要进展,心脏电起搏基本原理是用一定形式的脉冲电流刺激心肌,使传导功能有障碍的心肌,经起搏器电流刺激,而使心脏能激动,按一定的频率产生有效的收缩。目前临床上应用的起搏器系由刺激电极 It is known for a long time that current can excite the heart, but this knowledge, until recently, has been used clinically only by a single electrical stimulation that produces a contraction of the heart. Cardiac pacemakers for the treatment of arrhythmia, is an important progress in the treatment of heart disease in recent years, the basic principle of cardiac electrical pacing is to use certain forms of pulse current to stimulate the myocardium, conduction dysfunction of the myocardium, the pacer current stimulation , Leaving the heart can be excited, according to a certain frequency of effective contraction. The current clinical application of pacemaker by stimulating electrodes
