Transient junctional rhythm late after para-Hisian accessory pathway cryoablation occurred in two patients. Cryoablation was delivered using the 8 mm tip Freezor MAX™ catheter (Cryocath Technologies Inc., Montreal, Canada), 2 mm distal to the largest His potential. Transient symptomatic junctional rhythm occurred after 1 week. This benign, self-limiting rhythm is possibly caused by reversible cryoinjury to the His bundle periphery.
两名患者在希氏旁道消融术后出现短暂交界性节律。使用 8mm 头端 Freezor MAX™ 导管（Cryocath Technologies Inc.，加拿大蒙特利尔），距最大 His 电位 2mm 处进行冷冻消融。1 周后出现短暂症状性交界性节律。这种良性、自限性节律可能是由于希氏束周围的可逆性冷冻损伤所致。
