急性心肌梗死致一过性三度房室阻滞的临床探讨

The Clinical Research on Acute-myocardial-infarction-A transient Ⅲ°Atrioventricular Block

目的研究急性心肌梗死(AMI)致一过性三度房室阻滞。方法对207例AMI患者在入院48h内记录常规12导联或18导联心电图。结果 207例AMI中早期出现房室阻滞的有23例,其中三度房室阻滞有11例,出现阻滞的心肌梗死部位多数为下壁、正后壁、右室。结论急性下壁、正后壁、右室心肌梗死比其他部位心肌梗死更容易引起一过性三度房室阻滞。

Objective To study the acute -myocardial-infamtion-induced （AMI -induced） a transient Ⅲ°atrioventricular block. Methods Conventional 12 -lead records or 18 -lead ECG of 207 AMI patients were recorded within 48 hours after admitting to hospital Results 23 cases appeared atrioventricular block in 207 AMI patients in the early stage, of which Ⅲ degree atfioventrieular block in 11 cases, The block appears mostly in the parts of inferior wall, positive posterior wall and right ventricle. Conclusion Acute myocardial infarction in inferior wall, positive posterior wall and fight ventricle is more possible to cause a transient Ⅲ° atfioventricular block than in any other parts.
