Abstract
The aim of this study is to identify the features of ST-changes in 12-leads surface ECG, which help to diagnose the right ventricular involvement in inferior myocardial infarction. The study included 145 patients with inferior myocardial infarction, the right ventricular infarction (RVI) was detected by echocardiography in 62 (42.8%) patients. ST segment depression in lead aVL was deeper than in lead V3 in 93.5% of patients with RVI. This feature is revealed in 4.9% patients with inferior myocardial infarction without RVI only. The sensitivity of this criterion for diagnosis RVI is 93.5%, the specificity is 95.2%, the predictive value of positive and negative results make up 93.5 and 95.2%.
