观察 33例经左锁骨下静脉床旁紧急临时起搏的成功率 ,在无X线透视下将起搏电极经左锁骨下静脉盲插至右心室。多数病人( 2 9/33)一次性获得成功 ,少数 ( 3/33)进入左颈内静脉 ,1例失败。在无X线透视下经左锁骨下静脉插入电极导管至右心室起搏具有较高的成功率
The success rate of emergency temporary pacing near the bed of the left subclavian vein was observed in 33 cases. The pacemaker electrode was blindly inserted into the right ventricle through the left subclavian vein without fluoroscopy. Most patients (29/33) achieved a one-time success, a small number (3/33) into the left internal jugular vein, 1 case failed. In the absence of X-ray through the left subclavian vein into the lead to the right ventricular catheter pacing has a high success rate
