A 67-year-old male, suffering from ventricular tachycardia unresponsive to drug therapy, received a universal AV sequential pacemaker (DDD,M). The pacemaker was programmed in the DVI mode, pacing rate 100 bpm, AV interval 250 ms. After implantation, the patient experiences two episodes of tachycardia that proved to be pacemaker tachycardia with a rate of 150 bpm. The first period was self-terminating, and the second had to be stopped by reprogramming the pulse generator. Pacemaker tachycardia could easily be provoked by instructing the patient to contract the pectoral muscle adjacent to the pulse generator. To our knowledge, this is the first report of pacemaker tachycardia provoked by myopotentials in a pulse generator programmed in the DVI mode.
一名67岁男性，患有对药物治疗无反应的室性心动过速，植入了一台通用型房室顺序起搏器（DDD，M）。起搏器设置为DVI模式，起搏频率100次/分钟，房室间期250毫秒。植入后，患者经历了两次心动过速发作，经证实为起搏器介导的心动过速，心率为150次/分钟。第一次发作自行终止，第二次发作则通过重新设置脉冲发生器才得以终止。通过指导患者收缩靠近脉冲发生器的胸肌，很容易诱发起搏器介导的心动过速。据我们所知，这是关于在DVI模式下编程的脉冲发生器中，肌电位诱发起搏器介导的心动过速的首例报告。
