报道 9例心房颤动 (简称房颤 )患者在射频消融术中用经导管心房同步电除颤的结果。其中有房颤发作史者 5例 ,余 4例为心内电生理检查时诱发。房颤发作时采用普通电生理导管及消融导管在冠状窦与右心耳间放电。9例成功转复为窦性心律 ,平均放电 2 .2次 ,复律成功所需功率为 8.5 6± 4.95J。除 1例需 2 0J转复为窦性心律患者感轻度胸痛外 ,其余仅有心脏轻度震动感。所有患者均未用镇静剂 ,无并发症发生。
Reported 9 patients with atrial fibrillation (atrial fibrillation) in patients undergoing radiofrequency catheter ablation with atrial defibrillation results. Among them, there are 5 cases of atrial fibrillation attack, the remaining 4 cases were induced by intracardiac electrophysiological examination. Atrial fibrillation using ordinary electrophysiological catheter and ablation catheter in the coronary sinus and right atrial discharge. Nine patients successfully converted to sinus rhythm, with an average discharge of 2.2 times, the power required for successful cardioversion was 8.5 6 ± 4.95J. In addition to a case of patients need 20J sinus rhythm mild mild chest pain, the rest only mild heart vibration. All patients without sedation, no complications.
