The authors report the case of a 73-year-old patient presenting with polymorphous ventricular tachycardias one to 3 months after radiofrequency His bundle resection, as soon as the pacing frequency was reduced to 70 bpm. The clinical history revealed the existence of a possible clinical predisposition, as this patient had experienced an episode of torsade de pointe induced by hydroquinidine, one year previously. This case illustrates the importance of selecting a sufficiently high minimal stimulation frequency after His bundle resection.
作者报告了一例73岁患者的病例，该患者在射频希氏束切除术后1至3个月，一旦起搏频率降至70次/分钟，就出现了多形性室性心动过速。临床病史显示存在可能的临床易患因素，因为该患者在一年前曾经历过一次由氢醌诱发的尖端扭转型室速发作。该病例说明了希氏束切除术后选择足够高的最小刺激频率的重要性。
