摘　　要：目的　探讨心电图 P波异常对急性心肌梗死的影响。方法　选择 12 9例急性心肌梗死患者 ,根据心电图 P波的异常 (新出现的 )与否分为 :P波异常组 95例 ,P波正常组 34例。所有患者均行超声心动图、核素心血池、冠状动脉造影等检查 ,观察 12个月再梗死及死亡率。结果　心电图 P波异常组三支病变多见 ,P<0 .0 1;左室射血分数 <40 %者多见 ,P<0 .0 1;12个月时再发心肌梗死率为 7.4% ,死亡率为 4.2 % ,而 P波正常组无再发心肌梗死及死亡病例。结论　心电图Objective To explore the effects of abnormal P wave of ECG on acute myocardial infarction (AMI).Methods 129 cases suffering AMI were divided into two groups according to the new changes of P wave,group I (abnormal function of P wave )95 cases,group Ⅱ (normal P wave) 34 cases.All cases carried out the following examinations:UCG radionuclide technetium 99m blood pool imaging,coronary angiography reinfarction rate and mortality during 12 months were observed.Results Triple vessel lesion and cases with low left ventricle ejection fraction (<40%) were more common in group Ⅰ versus group Ⅱ ( P <0.01);the reinfarction rate and the mortality of 12 months were higher in group Ⅰ versus group Ⅱ (7.4% vs 0%,4.2% vs 0%).Conclusions Abnormal P wave of ECG may be an important factor affecting the prognosis of AMI.
