KLEiN和他的助手们论述了用冷冻外科的咝音式技术进行心脏房室结或房室束部分切除试验将22例中的17例病人的发病率降到最低限度。这种房室交界处的部分切除术使房室交界前的分枝传导通过正常通路即与房室结—房室束成为一个循环传导系统因而使复发性或慢性室上性快速心律失常完全治愈。在进行冷冻外科房室阻滞术后早期引起房室交界处逸搏节律平均达48次/分(范围40～72次/分)。这种节律作为冷冻外科房室阻滞的结果似乎在房室 KLEiN and his aides discussed the use of cryosurgical vernacular technique for partial atrioventricular node or atrioventricular block resection to minimize the incidence of 17 of 22 patients. Partial resection at the atrioventricular junction transforms the anterior branch of the atrioventricular compartment through the normal pathway, ie, the atrioventricular node-atrioventricular bundle, thereby completing the recurrent or chronic supraventricular tachyarrhythmia . In the early postoperative cryosurgery atrioventricular block caused by early atrioventricular junction escape rhythm average of 48 beats / min (range 40 ~ 72 beats / min). This rhythm appears to be in the atrioventricular compartment as a result of cryosurgical atrioventricular block
