急性心肌梗死并发各种不同类型心律失常的心电图变化和预后

Acute myocardial infarction complicated by the different types of ECG arrhythmia change and prognosis

目的讨论急性心肌梗死(AMI)患者发生各种心律失常的特征及预后情况。方法选择2000～2010年间确诊急性心肌梗死并发生心律失常的46例,对其心电图的动态变化描记、分析、比较,再回顾性分析。结果观察病例AMI患者以快速性心律失常多见,其中又以室性心律失常多见,并且AMI患者在其急性期发作心律失常危险性比较大,要及时发现并加以处理。结论在AMI患者中,由于梗死部位与非梗死部位复极不均匀,形成折返致心律失常,以室性心律失常为主,对AMI患者应密切监护心电图,及时处理,降低死亡率。

Objective To observe the characteristics and prognosis of patients with acute myocardial infarction in arrhythmia. Methods The 46 cases with acute myocardial infarction and arrhythmia from 2000 to 2010 were chosen, and the dynamic changes of their ECG were monitored , analyzed , compared and then retrospectively analyzed. Results Case observed in patients with acute myocardial infarction common tachyarrhythmia, which went ventricular arrhythmia common, and acute myocardial infarction in patients with acute attack of its dangerous arrhythmia more must be promptly i- dentified and dealt with. Conclusion In patients with acute myocardial infarction, because non - infarct and infarct site location depolarization uneven formation of reentrant arrhythmias, ventricnlar arrhythmia mainly on patients with acute myocardial infarction should closely monitor electrocardiogram, timely process to reduce death rate.
