摘　　要：心脏再同步治疗(CRT)与传统起搏治疗在适应证和植入技术上有很大不同。CRT治疗伴有收缩不同步的心衰患者,通常需要经静脉植入3根电极导线。其中通过冠状静脉窦植入左室电极导线来起搏左室,其起搏部位在CRT治疗中起相当重要的作用。有时还需寻求其它起搏模式,比如经胸植入左室电极导线来弥补冠状窦和静脉分支解剖所造成的治疗局限。除此之外,对右房、右室电极导线部位及起搏模式在CRT治疗中所起的作用也在进行各种优化探索。There are many differences between cardiac resynehronization therapy （CRT） and conventional pacing therapy in terms of indieations and implant techniques. Generally speaking, CRT requires implanting 3 pacing leads in heart failure patients with ventrieular dysynehrony. A left ventricular lead is implanted via intravenous coronary sinus. The pacing site of left ventricle has important influenee on therapy response. Sometimes open chest implant or other pacing modes are adopted to compensate the anatomical limitation of coronary sinus and its branches. In addition,the pacing sites and modes of right atrium and right ventriele are also under research to further improve CRT response.
