报道 2 5例 (男 14例、女 11例 ,年龄 15～ 6 7岁 )顽固性频发室性早搏 (简称室早 )伴短阵室性心动过速 (简称室速 )接受RFCA的治疗结果。采用心室激动顺序与起搏标测法进行室早标测定位 ,标测到室早最早激动点较体表心电图QRS波提前 30ms以上或消融电极起搏心电图QRS波图形与室早图形完全一致时放电消融。结果 :2 5例患者室早起源分别为右室流出道 12例、右室心尖部 5例、左室游离壁 5例、左室近后间隔部 3例。 2 5例中 2 1例成功 (包括 1例频发室早伴短阵多形性室速患者 ) ,成功率为 84 % ,无并发症发生。结论 :RFCA治疗频发单形性室早伴短阵室速安全、有效。
Report of 25 cases (14 males and 11 females, aged 15 to 67 years old) with refractory frequent ventricular premature beats (referred to as ventricular tachycardia) with paroxysmal ventricular tachycardia (VT) received RFCA treatment results . The ventricular activation sequence and pacemaker mapping method was used for early detection of ventricular mass. The earliest point of early detection of ventricular contractions was more than 30 ms earlier than QRS wave of body surface electrocardiogram (ECG) or QRS wave of electrocardiogram Discharge ablation. Results: The early origins of RV in 25 patients were 12 cases of right ventricular outflow tract, 5 cases of right ventricular apex, 5 cases of left ventricular free wall and 3 cases of proximal left ventricular compartment. Among 25 cases, 21 cases were successful (including 1 case of frequent premature ventricular tachycardia with pleiotropic pleomorphic VT), with a success rate of 84% without complications. Conclusion: RFCA treatment of frequent monomorphic ventricular tachycardia with mammography is safe and effective.
