| 摘 要： | 目的 探讨房室结前传文氏点和有效不应期与心房颤动时心室率的关系。方法 :36例阵发性房颤病人行食管电生理检查测房室结前传文氏点 (aWCL)和前传有效不应期 (aEPP) ,记录检查前最后一次房颤时的最快心室率 (MaVR)、最慢心室率 (MiVR)、平均心室率 (mVR)。结果 aWCL和aEPP与Ma VR、MiVR、mVR均呈负相关 ,与MaVR和mVR相关性较好 (P <0 0 5 )。结论 aWCL和aEPP的延长 ,可减慢房颤时的心室率 ,尤其是MaVR和mVR。

| Abstract: | Objective To discuss the reiationship between atrioventricuiar node (AVN ) antegrade wenckebach cycle length( aWCL) and ventricular rate during atrial fibrillation(Af).Methods 36 patients with paroxysmal Af(PAf) were examined aWCL and aEPP by esophagus electrophysiology checking.Record Maximum ventricular rate(MaVR) and minimum ventricular rate(MiVR) and mean vertricular rate(MVR) during the last Af before checking.Results MaVR and MVR and MiVR during Af were negatively correlated with aERP and aWCL, especially for MaVR and mVR(P<0.05).Conclution Probonging aWCL and aEPP could reduce ventricular rate, especially MaVR and mVR. |
