作者探讨了24例具有下后壁心肌梗塞尸解病例的心电图,认为ST段Ⅲ导高于Ⅱ导(比值Ⅲ/Ⅱ>1)可以诊断右室梗塞。并与右胸导联V_3R-V_7R,ST段抬高≥1mm诊断右室梗塞进行了比较。尸解所见24例病人均有左室梗塞,17例(占71%)伴有右室梗塞。右胸导联诊断右室梗塞特异性为100%,阳性预测值100%,而导联Ⅲ/Ⅱ>1比率诊断的特异性为88%。阳性预测值91%,两者之间
The authors examined the electrocardiogram of 24 patients with autopsy of the posterior wall of the posterior wall and concluded that right ventricular infarction may be diagnosed as a result of a higher grade ST segment III than a grade II (ratio III / II> 1). And right chest lead V_3R-V_7R, ST segment elevation ≥ 1mm diagnosis of right ventricular infarction were compared. The autopsy found that 24 patients had left ventricular infarction, 17 cases (71%) with right ventricular infarction. Right chest lead diagnosis of right ventricular infarction specificity was 100%, the positive predictive value of 100%, while the lead Ⅲ / Ⅱ> 1 diagnostic specificity of 88%. Positive predictive value of 91%, between the two
