The authors reviewed the results of 42 operations for non-ischemic ventricular tachycardias, tachycardia being arrested by laser ablation in 2 cases. Right and left ventricular tachycardias were seen in 26 and 14 patients, respectively. For diagnosis, preoperative electrophysiologic study, intraoperative epicardial mapping, and "delayed" potentials were used. In 38 of 40 patients who had undergone a direct operation, a positive result was obtained; in 31 patients, a complete disappearance without applying antiarrhythmics was observed. Four patients received drug therapy which proved to be ineffective before surgery. Two patients died after surgery due to recurrent tachycardia. Out of 38 survivals, 3 died of heart failure that was not caused by recurrent tachycardia.
作者回顾了42例非缺血性室性心动过速手术的结果，其中2例心动过速通过激光消融得以终止。分别有26例和14例患者出现右心室和左心室心动过速。诊断时采用了术前电生理研究、术中的心外膜标测以及“延迟”电位。在接受直接手术的40例患者中，38例获得了阳性结果；31例患者在未使用抗心律失常药物的情况下心动过速完全消失。4例患者在手术前接受了药物治疗，但证明无效。2例患者术后因复发性心动过速死亡。在38名存活患者中，3例死于并非由复发性心动过速引起的心力衰竭。
