We reported a 65-year-old man with symptomatic bradycardia caused by chronic atrial fibrillation who underwent pacemaker implantation by left bundle branch pacing (LBBP) via right subclavian vein (RSV) approach. A tricuspid valve annulus (TVA) angiography was performed, and a different connecting cable that can monitor electrocardiograms (ECG) and intracardiac electrograms (EGM) in real time was used during the process. By TVA angiography, we could easily find the ideal location of LBBP; a new connecting cable helped us avoid perforation and guide effective endpoint without the need to stop pacing. The case showed that it was feasible and safe to use the new method for LBBP through RSV route.
我们报告了一例 65 岁男性，因慢性心房颤动导致症状性心动过缓，经右锁骨下静脉（RSV）途径行左束支起搏（LBBP）植入起搏器。进行了三尖瓣环（TVA）血管造影，并在手术过程中使用了一种可以实时监测心电图（ECG）和心内电图（EGM）的不同连接电缆。通过 TVA 血管造影，我们可以轻松找到 LBBP 的理想位置；新的连接电缆有助于我们避免穿孔，并在无需停止起搏的情况下引导有效的终点。该病例表明，经 RSV 途径使用新方法行 LBBP 是可行且安全的。
