摘要
目的观察和比较伊布利特和胺碘酮转复心房颤动(房颤)射频消融术后早期复发房性心动过速(房速)的疗效和安全性。方法连续46例接受房颤射频消融后复发房速的患者,男性32例,女性14例,平均年龄(56±12)岁,分别静脉应用伊布利特(ibutilide,1.0mg/次,1~2次,10min内静脉推注)和胺碘酮(150me,/次,1~2次,10min内静脉推注)。观察转复率和转复时间,记录不良反应。结果4h内伊布利特组和胺碘酮组转复率分别为86.4%和41.7%(P=0.0023);24h时内转复率分别为90.9%和62.5%(P=0.0376)。伊布利特组对持续时间〈24h的房速转复率为100%,胺碘酮组转复率为66.7%(P=0.0421)。伊布利特组平均转复时间为(13±8)min,胺碘酮组转复时间为(364-25)min(P〈0.01)。两组均未发生致命性不良反应,不良反应发生率差异无统计学意义。结论伊布利特和胺碘酮均能终止射频消融术后复发房速,伊布利特更快速、安全、有效。
Objective To evaluate the immediate efficacy and safety of intravenous ibutilide and amio- darone for termination of recurrent atrial tachycardia after catheter ablation of atrial fibrillation. Methods Forty-six consecutive patients with recurrent atrial tachycardia less than 90 days who underwent catheter ablation of atrial fibrillation were enrolled in this study [ 32 male, 14 female, aged(56 ± 12)yearsJ. The patients were ran- domly assigned to receive infusion of ibutilide ( ibutilide group, 1 to 2 times, 1.0 mg for each) or amiodarone (amiodarone group, 1 to 2 times, 150 mg for each). Results Ibutilide was superior to amiodarone in treating recurrent atrial tachycardia after catheter ablation of atrial fibrillation ( 90. 9% vs 62.5%, P = 0. 0376 ). The mean response time was ( 13 ± 8 ) rain in ibutilide group and ( 36 ±25 ) rain in amiodarane group ( P 〈 0. 01 ). Conclusion Ibutilide can immediately terminate recurrent atrial tachycardia after catheter ablation of atrial fi- brillation safely and effectively.
