急性心肌梗死伴碎裂QRS波与室性心律失常

Relationship between fragmented QRS complex and ventricular arrhythmia in the cases of acute myocardial infarction

目的探讨心电图碎裂QRS波(QRSf)与急性心肌梗死(acute myocardial infarction,AMI)后出现恶性室性心律失常的关系。方法回顾性分析162例AMI者,根据其入院3天内心电图有无QRSf,分为QRSf组(A组)和无QRSf组(B组),对比观察两组住院期间各类室性早搏及室性心动过速,室扑室颤的发生率。结果 A组各类室早、室速、室扑/室颤的发生率显著高于B组(p<0.05)。结论急性心肌梗死后出现QRSf者与室性心律失常,尤其是恶性室性心律失常(VA)的发生密切相关,QRSf可作为AMI患者出现室性心律失常、尤其是恶性室性心律失常的预警指标。

Objective To research the relation ship between ventricular arrhythmia and QRSf in the cases of acute myocardial infarction（AMI）. Methods One hundred and sixty-two patients who were diagnosed as acute myocardial infarction were analyzed retrospectively. Samples were separated into two groups, group A covered those who existed QRSf in first 3 days after in hospital while group B covered those did not. Specially, the incidence of all kinds of premature ventricular contraction, ventricular tachycardia and ventricular fibrillation were compared. Results The incidence of all kinds of premature ventricular contraction, ventricular tachycardia and ventricular fibrillation in group A were significantly higher than group B（p0.05）. Conclusions The occurrences of QRSf in the cases of AMI and ventricular arrhythmia, especially malignant ventricular arrhythmia, are highly correlated. QRSf could be considered as an indicator of ventricular arrhythmia, especially malignant ventricular arrhythmia for AMI patients.
