Based on excellent results of successive single chest thumping (CT) and serial chest thumping (SCT) for the interruption of ventricular tachycardia (VT) in experimental animals with subacute myocardial infarction, the SCT method was applied for the treatment of VT in patients with coronary artery disease (CAD). SCT was successful in terminating 13 of 19 episodes of VT (68%) in 8 of 14 patients (57%). Conversion of VT was immediate in 9 episodes in 6 patients and latent in 4 episodes in 2 patients. Complications were rare but significant. In one case, SCT resulted in a ventricular asystole and in another case SCT accelerated the rate of VT from 167/min to 242/min, requiring electroconversion. Neither a short duration of VT nor a preserved left ventricular function seemed to enhance conversion by SCT. For interruption of VT in patients with CAD, SCT is not as successful as in the experimental animal model and, therefore, should not be used as a routine method. It may be applied in selected patients under hospital conditions with a standby defibrillator.
基于连续单次胸部叩击（CT）和连续胸部叩击（SCT）在亚急性心肌梗死实验动物中成功中断室性心动过速（VT）的出色结果，SCT方法被应用于冠状动脉疾病（CAD）患者室性心动过速的治疗。SCT成功终止了14例患者中8例（57%）的19次室性心动过速发作中的13次（68%）。6例患者的9次发作中室性心动过速立即转复，2例患者的4次发作中延迟转复。并发症虽罕见但严重。1例中，SCT导致心室停搏，另1例中SCT使室性心动过速的速率从167次/分钟加速至242次/分钟，需进行电复律。室性心动过速持续时间短和左心室功能保留似乎均未增强SCT的转复效果。对于CAD患者室性心动过速的中断，SCT不如在实验动物模型中那样成功，因此，不应作为常规方法使用。它可在有备用除颤器的医院条件下应用于选定患者。
