摘要
将240例急性心肌梗塞(AMI)患者分成单纯AMI组、心律失常组、左心衰组、心源性休克组.分别对各组治疗前、后4周内及5～12周心电图Ptf_v(?)的动态变化进行对比研究.结果Ptf_v(?)异常发生率及其负值在各组差异均有显著性(P<0.05).发现AMI早期阶段Ptf_v(?)负值大,随着病情恢复负值变小,在合并左心衰或心源性休克时更为明显.它是反映左心功能变化直观、简单、敏感的指标;也应是AMI预后指标之一.Ptf_v(?)<-O.03mm·s强烈提示左心功能不全,<-O.04mm·s预后不良.
To investigate the dynamical changes and clinical significance of Ptfv1 in patients with acute myocardial infarction (AMI) ,240 cases of AMI were divided into four groups:simple AMI; AMI with arrhythmia (AMI with left heart failure and AMI with cardiac shock for comparison of the dynamical changes in Ptfvi of electrocardiogram 4 weeks and 5 12 weeks before and after treatment. The results showed that there were significant differences in abnormal incidence of Ptfvi and its value among the four groups (P< 0. 05). In the early stage,patients with AMI had the highest negative value of Ptfv1,especially in AMI patients complicated by left heart failure or cardiac shock. But the negative value of Ptfv1 decreased with the patient's recovery. We concluded that Ptfvi is an objective,simple and sensitive indicator for left heart failure and a good predictor for the prognosis of patients with AMI. It is strongly suggested that there is left heart insufficiency in patients with AMI if Ptfv1 is less than - 0. 03 mm·s and worse prognosis if Ptfv1 less than -0. 04mm·s.
