急性右室梗死心向量图分析

Vectorcardiogram of Acute Right Ventricle Infarction

目的通过心电图(ECG)与心向量图(VCG)同时记录分析,及时发现诊断急性右室梗死(ARVI)。方法选自临床诊断明确,心肌酶谱(CK-MB)升高,有典型急性右室梗死ECG与VCG资料。分析在有或无左室梗死条件下急性右室梗死心向量图改变。结果 4例ARVI以ST向量向右侧增大为主要特点。单纯右室梗死ST向量指向右上方,伴有下壁梗死ST向量指向右前下方,伴有下、后壁梗死的ST向量指向右后下方。结论 VCG对ARVI有较高的诊断价值。

Objective To detect and diagnose acute right ventricle infarction timely through ECG and VCG,simultaneously recording and analyzing.Method Selected from the ECG and VCG data of cases with an increased myocardial zymogram（CK-MB,etc.）,and definitely clinically diagnosed of typical acute right ventricle infarction.Analyze VCG changes of ARVI with and without the condition of inferior,posterior infarction of left ventricle.Result 4 cases ARVI mainly featured in a rightward enlarged ST vector.ST vector of simple right ventricle infarction pointed at upper right;with an inferior infarction,pointed at lower right front;with inferior posterior infarction,pointed at lower right back.Conclusion VCG has a high diagnostic value for ARVI.
