We report on a case where a temporary pacing wire that was inserted through the left internal jugular vein was subsequently noted to follow an unusual course on the chest radiograph. A 12-lead electrocardiogram showed right bundle branch block pattern during pacing, suggesting that the lead was pacing the left ventricle. Computed tomography of the chest demonstrated that the likely path of the pacing wire was through an anomalous vein that originated from the left subclavian vein and drained into the left atrium. The importance of paying careful attention to the chest radiograph and electrocardiogram after transvenous pacing are discussed.
我们报告了一例通过左颈内静脉插入的临时起搏导线，随后在胸部 X 线片上发现其走行异常。12 导联心电图显示起搏时呈右束支传导阻滞图形，提示导线起搏左心室。胸部 CT 显示起搏导线可能经过一条起源于左锁骨下静脉并汇入左心房的异常静脉。讨论了经静脉起搏后仔细观察胸部 X 线片和心电图的重要性。
