摘　　要：①目的　探讨最大P波时限 (Pmax)、P波离散度 (Pd)和P波时限变异 (Pv)预测急性心肌梗死并发阵发性心房颤动的意义。②方法　观察 4 0例急性心肌梗死并发阵发性心房颤动病人 (Ⅰ组 )的Pmax、Pd、Pv ,并与 4 0例急性心肌梗死无并发阵发性心房颤动的病人 (Ⅱ组 )比较。③结果　Ⅰ组病人Pmax、Pd和Pv显著大于Ⅱ组 (t=2 .79～ 6 .6 2 ,P <0 .0 1 )。Pmax为 1 1 0ms、Pd为 4 0ms、Pv为 1 80ms2 时三者预测急性心肌梗死并发阵发性心房颤动的灵敏度分别是 78%、74 %、70 % ,特异度分别是 77.35 %、6 9.6 2 %、6 7.75 %。④结论　Pmax。Objective To evaluate the significance of P wave duration (Pv), P wave dispersion (Pd) and variance of P wave duration in the prediction of acute myocardial infarction(AMI) complicating paroxysmal atrial fibrillation(PAF). Methods The maximum P wave duration(Pmax), P wave dispersion and variance of P wave duration from the 12-lead surface electrocardiogram of 40 AMI patients with PAF(Group A) and 40 without(Group B) were measured. Results Pmax, Pd and Pv were significantly higher in Group A than in Group B ( t=2.79-6.62, P <0.01). Pmax value of 110 ms, Pd value of 40 ms, and Pv value of 180 ms 2 separated patients from controls with a sensitivity of 78%, 74%, and 70% , respectively ,and a specificity of 77.35%, 69.62%, and 67.75%, respectively. Conclusion Pmax, Pd and Pv are electrocardiographic markers that could be used for the prediction of acute myocardial infarction patients at risk of PAF.
