查询词典 electrodes

The causes were right auricle injury by violently placing a electric catheter to it (n=2),coronary sinusinjury by violently placing a electric catheter to distal CS (n=3) and by intracardiac electric defibrillation using electric catheter electrodes of high right atrium and CS as current loop(n=1),perforations of right atrial wall (n=3) and left atrial wall(n=2) by sliding up of the transseptal set,and perforation of left auricle by misplacing the mapping catheter of left superior pulmonary vein to it (n=1). 10 cases of acute tamponade occurred during operation, and 2 after operation.12 patients were treated successfully with urgent pericardiocentesis, and no patients required emergency surgery.

引起心包填塞的原因有：①放置电极导管至右心耳时用力过大致右心耳损伤(2例)；②放置电极导管至冠状静脉窦时，因导管不易进入远端而用力过大致CS损伤(3例)；③心内电除颤时采用高位右房和CS电极作回路，致CS损伤(1例)；④房间隔穿刺系统向上滑动穿破右房(3例)和左房(2例)；⑤放置左上肺静脉标测电极时导管误入左心耳致其穿孔(1例)。10例急性心包填塞出现于术中，另2例术后发生。12例患者经紧急心包穿刺引流均成功治愈，无1例需外科急诊手术。
