The relationship between electrocardiogram and infarction-related artery in 69 cases of acute inferior myocardial infarction

Geng Liming

Abstract

The results of electrocardiogram and coronary angiography were compared in 69 patients with acute inferior myocardial infarction(right ventricle, later wall). The sensitivity and specificity of ST segment elevation Ⅲ> Ⅱ in diagnosis of right coronary artery (RCA) as the infarction related artery (IRA) were 92.00% and 84. 21% respectively;those for ST segment depression avL > Ⅰ were 90. 00% and 89. 5% respectively. Therefore if ST-elevation Ⅲ > Ⅱ , ST-depression avL > Ⅰ and no depression on STV1 and V2 in acute inferior myocardial infarction may highly indicate that RAC be the IRA;on the contrary, the LCX be the IRA. Key words: Myocardial infarction; Electrocardiography
