摘要
目的：评估急性心肌梗塞（AMI）恢复后心电图V1导联P波终末电势（Ptfv1）的远期预后价值。方法：将113名AMI恢复期患者（起病后第4～5周）分为Ptfv1阳性（≤－0．03mm·s）组及阴性组，比较两组门核素左室射血分数（LVEF）及超声左室内径（LVD），平均随访23．4个月。结果；阳性组LVEF低（P＜0．01）；阳性组LVD较大（P＜0．05）；随访期，阳性组死亡及心衰、严重心律失常（室速及室颤）发生率高（P＜0．01及0．005），而两组间再梗塞及不稳定型心绞痛发生率无明显差异。结论：AMI恢复期Ptfv1对AMI的远期预后评估有显著价值。Ptfv1阳性预示死亡、心衰及严重心律失常发生率高。
OBJECTIVE:To evaluate the long-term prognostic val-ue of the terminal force of P wave in lead V1()5fv1)on elec-trocardiogram (ECG)in patients with acute myocardial infare-tion(AMI). METHOD:113 patients with AMI in the fourth or fifth week after the onset were divided into Ptfv1 positive (<- 0.03mm . s) and negative groups. The average follow-upperiod was 23. 4 months. RESULT: In the positive group ,the left ventricular ejection fraction was low(P<0.Ol ) and the left ventricular size was large(p< 0.O5 ). In the follow-upperiod ,the mortality rate and the incidence of heart failure,ventricular tachycardia and ventricular fibrillation were higher in positive group(p < O .0l, P < 0.005),, while there was no difference in the incidence of reinfarction and unstable angina pectoria between the two groups. CONCLUSION:Ptfv1 has long - term prognostic value in patients with AMI. Ptfv1 posi-tive (< 0. 03mm. s) is a predictor of increased mortality and critical ventricular arrhythmia in the years after infarction.
