Prognostic value of ST segment elevation in additional right ECG leads in patients with inferior myocardial infarction

The article presents data on the prognostic value of ST segment elevation on an electrocardiogram in additional right chest leads V3R-V4R during the acute period of myocardial infarction in patients with inferior wall myocardial infarction. The study included patients with inferior wall myocardial infarction (n=101) aged 34 to 85 years. Elevation of the ST segment in leads V3R-V4R ≥0.5 mV was observed in 35 patients (35%). It was revealed that the ST segment elevation in the V3R-V4R leads is an unfavorable prognostic sign in terms of the risk of arterial hypotension in the acute period of myocardial infarction, heart rhythm disturbances, and hemodynamically significant sinus bradycardia.
