The present study attempts to analyze the sensitivity and specificity of the S-T segment depression in I and a VL leads in the diagnosis of postero-inferior myocardial infarction with right ventricular extension. Thirty four specimens from autopsies performed in the Instituto Nacional de Cardiología Ignacio Chávez with histopathological evidence of postero-inferior myocardial infarction, with an adequate clinical, enzymatic and electrocardiographic documentation were studied. In 23 the postero-inferior myocardial infarction had extended to the right ventricle (group I) and in ll only left ventricle was involved (group II). There were not significative differences in severity and extension of coronary obstructions between the two groups studied. Sensitivity of S-T segment depression in DI lead ad diagnosis of right ventricular extension had 82.6%, specificity 90.9%, positive predictive value 95%, negative predictive value 71.4% and diagnostic efficiency 85.2%. Sensitivity of S-T segment depression in a VL lead as diagnostic of right ventricular extension was 91.3%, specificity 81.8%, positive predictive value 91.3%, negative predictive value 81.8% and diagnostic efficiency 88.2%.
