摘　　要：目的探讨急性心肌梗死并发心房颤动与P波最大时间 (Pmax)、P波离散度 (Pd)的关系。方法观察31例急性心肌梗死并发阵发性心房颤动患者和20例单纯急性心肌梗死患者的Pmax、Pd 。结果两组Pmax(124.32±3.58、110.77±2.62ms)、Pd(45.75±2.76、29.08±3.87ms)差异均有非常显著性意义 (P<0.01) ;Pmax≥120ms和Pd≥40ms预测心房颤动的敏感性分别为93%和97% ,特异性分别为91 %和96 %。结论Pmax 延长和Pd 增加可预测急性心肌梗死并发心房颤动的危险性。Objective To understand relationship between acute myocardial infarction mith paroxysmal atrial fibrilation and P wave dispersion(P d) and maximum P wave interval(Pmax). Methods Acute myocardial infarction with paroxysmal infarction con_trol group were observed Pmax and Pd. Results Pmax (124.32±3.58 vs.110.77±2.62 ms)and P d (45.75±2.76 vs.29.08±3.87 ms)had significant difference between acute myocardial infarction with PAF and contral group,Pmax≥120 ms and Pd≥40 ms separated patients from control group,with a higher sensitivity(93% and 97%)and specificity(91% and 96%).Conclusion A prolonged Pmax and a increased Pd may be predictive risk of acute myocardial infarction with paroxysmal atrial fibrillation.
