【摘要】 目的分析非心房颤动(简称房颤)患者肺静脉电位(PVP)的特点.并探讨其临床意义。方法选择需经房间隔穿刺行射频消融术的左侧旁道引起的房室折返性心动过速患者,普通射频消融术后,根据肺静脉逆行造影显示的肺静脉大小、位置,放置环状标测导管(Lasso肺静脉标测电极),依次记录左上肺静脉(LSPV)、左下肺静脉(LIPV)、右上肺静脉(RSPV)、右下肺静脉(RIPV)的双极电图,并与体表心电图、冠状静脉窦电图同步记录。结果共标测肺静脉49根,PVP表现为单一、规律的电活动,呈现PVP2A(心房远场电位)或A2PVP传导,但PVP落后于冠状静脉窦电极标测的心房波。结论非房颤患者PVP的存在也具有普遍性。更多还原

【Abstract】 Objective To study the characteristics of pulmonary vein potential(PVP) in subjectswithout atrial fibrillation(AF).Methods Patients undergoing transep tal radiofrequency catheter ablation(RFCA) for left atrioventricular reentrant tachycardia were selected to study.After successful RFCA p rocedure,Selective pulmonary vein (PV) venography through 8F Swartz catheter allowed p lacement of an app rop riate size decapolar performed circular catheter(Lasso) in the PVs,Bipolar electrogrames of PVswere recorded on a multichannel polygraphywith surface ECG, coronary vena sinus atrialelectrogrames.Result Forty nine PVswere examed,whose PVPswere mono morphogeny, regular electric activity,order of PVP and A(far field atrial potential) was variable,and most PVPswere slower than atrial potential in coronary sinus.Conclusion PVP can be recorded in every subjectswithoutAF.更多还原
