The left ventricular lead was implanted in branch of coronary sinus, 16 in great cardiac vein, 9 in latherier vein, 21 in latherier posterior vein, 23 in posterior vein and 2 in middle cardiac vein.
左心室起搏电极导线植入不同的冠状静脉窦分支，其中，心大静脉16例，心侧静脉9例，心侧后静脉21例，心后静脉23例，心中静脉2例。
All of them received three chamber biventricular pacing and the left ventricular pacing lead was inserted into a cardiac vein through coronary sinus.
患者均进行了三腔双心室同步起搏，起搏电极导线分别置于右心房、右心室以及经由冠状静脉窦置于一支心脏静脉起搏左心室。
Conclusion the ordinary ventricle lead, which is cheap, is feasible and safe for left atrium pacing through the middle and distal part of the coronary sinus and suitable for clinical application.
结论普通心室电极经冠状窦中、远端行左心房起搏可行、安全，且价格便宜，适合临床应用。
