摘要
目的探讨心电图碎裂QRS波(QRSf)与急性心肌梗死(AMI)后出现恶性室性心律失常的关系。方法 162例急性心肌梗死者均行十二导联心电图检查,出现QRSf 101例(A组),无QRSf 61例(B组),观察两组住院期间各类室性期前收缩及室性心动过速,心室扑动/心室颤动的发生率。结果 A组各类室性期前收缩、室性心动过速、心室扑动/心室颤动的发生率显著高于B组(P<0.05)。结论急性心肌梗死后出现QRSf者,室性心律失常,尤其是恶性室性心律失常(VA)发生率高,QRSf可作为急性心肌梗死患者出现室性心律失常、尤其是VA的预警指标。
Objective To research the relation between ventricular arrhythmia and QRSf in acute myocardial infarction（AMI）.Methods One hundred and sixty-two patients who were diagnosed as AMI by 12-lead ECGs were separated into two groups.Group A covered those who existed QRSf in first 3 days after in hospital while group B covered those had not.The incidence of all kinds of premature ventricular contraction,ventricular tachycardia and ventricular fibrillation were compared between the two groups.Results The incidences of all kinds of premature ventricular contraction,ventricular tachycardia and ventricular fibrillation in group A were significantly higher than those in group B（P0.05）.Conclusion The occurrences of QRSf in the cases of AMI and ventricular arrhythmia,especially malignant ventricular arrhythmia（MVA）,are highly correlated.QRSf could be considered as an indicator of ventricular arrhythmia,especially of malignant ventricular arrhythmia for AMI patients.
