常规12导联心电图诊断急性右室心肌梗死的意义

Significance of diagnosing acute myocardial infarction of right ventricle with routine 12 lead ECG

目的 探讨常规 12导联心电图诊断急性右室心肌梗死的意义。方法 分别以 6项诊断标准对34例急性下壁心肌梗死合并右室梗死进行分析 ,同时观察心电图改变的持续时间 ,并与 35例单纯下壁心肌梗死对照。结果 6项诊断标准均具一定的敏感度和特异度。单纯下壁心肌梗死时符合上述诊断标准的远少于合并右室梗死者 ,两者比较 ,除一项标准外 ,差异均有显著意义 ,且常规导联改变持续时间较右胸前导联持续时间长。结论 急性下壁心肌梗死时 ,通过常规 12导联分析可以诊断合并急性右室心肌梗死 ,同时可观察时间较右室导联更长。

Objective To explore the significance of diagnosing acute myocardial infarction of right ventricle with routine 12 lead ECG.Methods According to the six diagnostic standards separately,34 cases of acute inferior pooled myocardial infarction of rigth ventricle were analyzed and compared with the 35 cases of simple inferior myocardial infarction.The duration of ECG changes was observed simultaneously.Results The six diagnosis standards had definite sensitivity and specificity.Much less cases of simple inferior myocardial infarction coincided with the diagnosis standards than those of the acute inferior pooled myocardial infarction of right ventricle.The difference was remarkable except for one diagnosis standard when they were compared.And the duration of lead change was longer than that of right thoracic.Conclusion It's possible to diagnose the acute inferior pooled myocardial infarction of right ventricle with 12 lead analyses and at the same time the observation time is longer than that of right thoracic.
