目的:探讨心电图引导下用普通电极导管行紧急床旁临时心脏起搏术的安全性和有效性。方法:35例不同病因所致严重缓慢型心律失常、心脏骤停者,采用非X线条件下,应用普通电极导管,以心腔内心电图引导,体表起搏心电图定位,行紧急床旁临时心脏起搏术。结果:35例患者起搏均获成功,从开始静脉穿刺到完成右心室起搏时间5~20 min,平均13 min。35例均为右心室起搏,右室心尖部起搏29例,右室流出道起搏5例,右室流入道起搏1例。结论:心腔内心电图引导,体表起搏心电图定位,普通电极导管床旁起搏术是一种效果可靠,操作简便,安全实用的抢救措施,对临床具有重要意义。
Objective: To investigate the safety and efficacy of emergency bedside temporary cardiac pacing under general electrocardiogram guided electrocardiogram (ECG). Methods: Thirty-five patients with severe arrhythmia and cardiac arrest due to different etiologies were enrolled in this study. Under non-X-ray conditions, normal lead was used. Echocardiographic guidance, Cardiac pacing. Results: Twenty-five patients had successful pacing, with a mean time of 13 min from the start of venipuncture to the completion of right ventricular pacing time of 5 to 20 min. All the 35 cases were right ventricular pacing, right ventricular apical pacing in 29 cases, right ventricular outflow tract pacing in 5 cases, right ventricular inflow pacing in 1 case. Conclusions: Intracardiac electrocardiogram guidance, surface pacing electrocardiogram localization, and common electrode catheter bedside pacing are reliable and simple, safe and practical rescue measures, which are of great significance to clinical practice.
