Pacemaker dependent patients exhibit interventricular conduction delay due to right ventricular lead placement. The addition of a transvenous coronary sinus lead for biventricular pacing has been shown to be effective. Venous stenosis and thrombosis postpacemaker implantation can occur in up to 35% of patients. This report describes a patient with a preexisting left-sided dual chamber pacemaker and chronic left subclavian vein occlusion that was upgraded to a biventricular system byplacing a coronary sinus lead and single chamber ventricular triggered pacemaker on the opposite side.
起搏器依赖型患者由于右心室电极植入而出现室间传导延迟。已证明添加经静脉冠状窦电极进行双心室起搏是有效的。起搏器植入后静脉狭窄和血栓形成发生率高达35%。本报告描述了一名已有左侧双腔起搏器和慢性左锁骨下静脉闭塞的患者，通过在对侧植入冠状窦电极和单腔心室触发起搏器，升级为双心室系统。
