An experimental study in an electrophysiological model of the human body showed defibrillator discharge current, used for closed electrodestruction of His' bundle in cases of drug-resistant supraventricular tachycardias, to cause a spark discharge and high-energy shock wave around the intracardiac electrode resulting in contusion of the heart. To stop the sparking, it is suggested that impulse voltage should be reduced while its duration should be prolonged in order to maintain local destruction potential. The relationship between the damaging effect of the impulse, and its force and duration was examined so that optimum action parameters could be established.
在人体电生理模型上进行的一项实验研究表明，用于药物难治性室上性心动过速病例中希氏束闭合性电毁损的除颤器放电电流，会在心内电极周围引起火花放电和高能冲击波，从而导致心脏挫伤。为了停止火花放电，建议降低脉冲电压，同时延长其持续时间，以维持局部破坏电位。研究了脉冲的损伤效应与其强度和持续时间之间的关系，以便确定最佳作用参数。
