经右锁骨上锁骨下静脉穿刺导入自制丁形轨道管,将丁形弯头旋向身体左前45°,通过轨道管可将右心导管、心内膜心肌活检钳、漂浮导管等迅速插入右室。本法有助于选择性进入预定途径(如冠状窦),可缩短操作时间,减少X线损害。右室起搏最具优点,不需X线,是床边紧急起搏的良好方法。
The right clavicle through the subclavian vein puncture into the homemade T-shaped track tube, the small bends elbow to the front left body 45 °, through the track tube can right heart catheterization, endocardial biopsy forceps, floating catheter and so quickly inserted into the right ventricle . This method helps to selectively enter the intended route (such as coronary sinus), can shorten the operation time and reduce X-ray damage. Right ventricular pacing the most advantages, without X-ray, bedside emergency pacing is a good method.
