利用外源性电流来治疗心律失常,是一个重大的进展。1947年Beck等首先在临床上用交流电成功地消除了心室纤颤。1962年Lown等进一步用直流电纠正心室纤颤获得成功。近20年来,由于电击复律和心脏起搏器的广泛应用,心律失常的治疗有了很大的进展,大大降低了心律失常患者的死亡率。电击复律就是以电击心脏(胸内或胸外)使心律失常转为窦性心律。这通常称为“除 The use of exogenous current to treat arrhythmias is a major advance. In 1947, Beck et al first successfully eliminated ventricular fibrillation with alternating current in clinic. In 1962, Lown et al. Further used DC to correct ventricular fibrillation. In the past 20 years, the treatment of arrhythmia has made great progress due to the extensive application of cardioversion and pacemakers, greatly reducing the mortality rate of arrhythmia patients. Electrical shock cardioversion is to shock the heart (intrathoracic or chest) so that arrhythmia into sinus rhythm. This is commonly called "except
