摘　　要：目的:探讨心房晚电位预测阵发性心房颤动的价值。方法:以P波触发体表信号平均心电图记录技术测试55例老年人(正常组),35例有单发房性早搏者(房早组)及50例阵发性心房颤动患者(房颤组)的心房晚电位(包括滤波后P波时限,P波终末20 ms、30 ms、40 ms的电压均方根值)并进行比较分析。结果:滤波后P波时限:较之正常组与房早组,房颤组的显著延长(P<0.01),正常组与房早组无显著差异(P>0.05)。P波终末20 ms电压均方根值:正常组为(5.89±2.07)μV,房早组为(5.03±2.04)μV,房颤组为(3.96±1.80)μV,较之正常组与房早组,房颤组的显著降低(P<0.01,P<0.05),正常组与房早组无显著差异(P>0.05);P波终末30 ms电压均方根值:较之正常组、房早组,房颤组的显著降低(P<0.01.P<0.05).房早组亦较正常组显著降低(P<0.05)。结论:P波触发体表信号平均心电图记录心房晚电位可作为预测阵发性心房颤动的一个快速、无创性指标。Objective: To explore the value of atrial late potential (ALP) predicting paroxysmal atrial fibrillation (PAF) in aged person. Methods :Fifty five aged persons (normal group) , 35 patients with atrial premature beat (APB, APB group) and 50 patients with PAF (PAF group) had their ALP measured [contain : The P wave duration after filtered (Ad), mean roof square (MRS) of voltages for the last 20 ms (LP20), 30 ms (LP30) and 40 ms (LP40)] with the P waves\|triggered signal-averaged electrocardiogram and comparatively analyzed. Results: Ad: Compared with normal group and APB group the Ad of PAF group significantly increased (F<0. 01), there was no significant difference between normal group and APB group (P>0. 05). LP20 significantly decreased in AF group than that in normal group and APB group (3. 96±1. 80 μV vs 5. 89±2. 07 μV, P<0. 01 and vs 5. 03±2. 04 μV, P<0.05), there was no significant difference between normal group and APB group (P>0. 05). Compared with normal group and APB group the LP30 of PAF group significantly decreased (P<0. 01, P<0. 05); the LP30 of PAF group was significantly less than APB group (P<0. 05). Conclusion: Atrial late potential may be a non-traumatic index to predict paroxysmal atrial fibrillation.
