| 摘 要： | 目的 观察心房颤动 (房颤 )患者的心房传导性及心房不应期 ,探讨房颤发生机制。方法 以既往无房颤病史、在心脏电生理检查中出现房颤的 72例非器质性心脏病患者作为研究对象 ,测量反映心房传导的电生理参数 (P A、P CSd、S1 A1、最大S2 A2、MaxCD、CDzone)及心房有效不应期(ERPHRA) ,与同等条件下无房颤发作的患者进行比较。结果 房颤组P A、P CSd、最大S2 A2、MaxCD、CDzone显著延长 (P =0 0 0 1) ,ERPHRA 明显缩短 (P =0 0 0 1)。结论 心房传导性的降低和心房有效不应期的缩短是房颤发生的心房电生理基础

| Abstract: | Objective To investigate the electrophysiological characteristics of the atrium in patients with atrial fibrillation (AF) during electrophysiological study (EPS) Methods Seventy two patients with presence of AF during EPS were selected as Group AF , and the other 78 patients without AF as Group control All the patients had no AF history and structural heart diseases P A, P CSd, S1 A1, S2 A2, Max CD, CD zone and ERP HRA were measured as the electrophysiological parameters Results P A, P CSd, S1 A1, S2 A2, Max CD and CD zone were significantly longer in Group AF than in Group control , ERP HRA was shorter in Group AF Conclusion The decreased atrial conduction and the shorter atrial effective refractory period may be the electrophysiological basis for the occurrence of AF |
