我们对2例扩张型心肌病（DCM）和1例致心律失常性右心室发育不良（ARVD）患者的室性心动过速（VT）进行了射频消融（RF消融）。患者1患有与DCM相关的持续性VT。进行射频消融，记录舒张期电位，并显示隐匿性夹带。通过射频消融终止室性心动过速。患者2患有与ARVD相关的耐药VT。进行射频消融，在窦性心律期间获得完美的起搏标测，记录舒张电位，并证明隐藏的夹带。通过射频消融终止室性心动过速。患者3有2个形态学上不同的与DCM相关的VT。射频消融的靶点为2例中的1例，为耐药型。在记录延迟电位的位置获得了完美的起搏标测。随着起搏电流强度的降低，QRS波群构型转换为另一种类型。该部位被认为是两种类型折返环路的共同慢传导区，在该部位进行了射频消融。在这3例病例中，室性心动过速在消融术后未复发。射频消融是治疗心肌病相关室性心动过速的有效方法。
We performed radiofrequency catheter ablation (RF ablation) for ventricular tachycardia (VT) in 2 patients with dilated cardiomyopathy (DCM) and 1 patient with arrhythmogenic right ventricular dysplasia (ARVD). Patient 1 had incessant VT associated with DCM. RF ablation was performed where diastolic potentials were recorded and concealed entrainment was demonstrated. VT was terminated by RF ablation. Patient 2 had drug-resistant VT associated with ARVD. RF ablation was performed where perfect pace-mapping was obtained during sinus rhythm, diastolic potentials were recorded and concealed entrainment was demonstrated. VT was terminated by RF ablation. Patient 3 had 2 morphologically distinct VTs associated with DCM. The target for RF ablation was 1 of the 2, which was a drug-resistant type. Perfect pace mapping was obtained where delayed potentials were recorded. As the current strength of pacing was reduced, the QRS complex configuration switched to the other type. This site was thought to be the common slow conduction zone for the re-entry circuit of the 2 types and RF ablation was performed at this site. In these 3 cases, VT did not recur after ablation. RF ablation is effective for the treatment of VT associated with cardiomyopathy.
