摘 要：目的：探讨床旁临时心脏起搏在抢救严重缓慢性心律失常患者的应用价值。方法：严重缓慢性心律失常患者28例，均经床旁左锁骨下静脉置入起搏电极，观察心电图图形，判断电极位置。结果：28例患者均右心室起搏成功，从开始穿刺到起搏成功均≤15min。所有病例于成功起搏后血流动力学明显改善，经原发病治疗后心律失常得到有效控制。结论：床旁临时心脏起搏术在抢救严重缓慢性心律失常患者的疗效确切，是严重缓慢性心律失常或心脏骤停的重要抢救技术之一。

    Abstract: Objective: By using beside emergency temporary cardiac pacing through left subclavicular vien without the direction of X-ray. Method: 28 patients suffered from chronic serious bradycardia and marked heamodynamic discorder were treated . The pacemaker electrode position in right ventricle and cardiac paceing could be estimated by use of superficial ECG. Result: All 28 patients were successfully paced. Period from puncturing to successful pacing was less 15 min. Conclusion: In this paper , how to improve the success rate of puncture , prevent misleading the catheter into subclavicular artery of vein were discussed. ......
