We performed electrical catheter ablation (ECA) in a patient who had old myocardial infarction and drug-refractory sustained ventricular tachycardia (VT). ECA using 100J to the earliest activation site and the pace-mapping site failed to prevent the VT. ECA using the same energy to the site at which mid-diastolic potential was recorded during tachycardia could successfully ablate the VT. Therefore the site of energy delivery was important in VT with old myocardial infarction.
我们对一名患有陈旧性心肌梗死且药物难治性持续性室性心动过速（VT）的患者进行了电导管消融（ECA）。对最早激动部位和起搏标测部位使用100焦耳的ECA未能预防VT。对心动过速期间记录到舒张中期电位的部位使用相同能量的ECA能够成功消融VT。因此，能量释放部位在陈旧性心肌梗死所致VT中很重要。
