无X线指导紧急临时心脏起搏治疗重症慢性心律失常24例临床观察

TWENTY-FOUR CASES WITH SEVERE BRADYCARDIA TREATED WITH EMERGENCY TEMPORARY PACING WITHOUT THE DIRECTION OF X-RAY

对24例急性重症缓慢性心律失常合并严重血流动力学障碍患者进行无X线指导下床旁紧急临时心脏起搏治疗，以体表心电图和边进导管边起搏的方法判断起搏情况及电极的位置。结果成功起搏22例，成功率gi．7％。本文还对其临床意义及并发症的预防进行了讨论。

By using bedside temporary cardiac pacing through left subclavicular vein or rightfemoral vein without the direction of X - ray, 24 patients suffered from severe bradycardia and markedhaemodynamic disorder were treated. The pacing electrode positioned in right ventricular and cardiac pacing could be estimated by use of surface EKG. 22 patients were successfully paced. Timedmation frompuncturing to successful pacing was 2. 68 t 2. 2min. The improvement of the success rate of punctureand the prevention of the c0mplication were discussed.
