[Information value of right precordial ECG leads in the diagnosis of right ventricular myocardial infarct].

An analysis of the right ECG precordial leads in 61 patients with left ventricular posteroinferior myocardial infarction and in 55 patients with combined affection of the right and left ventricular posteroinferior walls revealed a high informative value of ST segment elevation for recognition of right ventricular myocardial infarction on the 1st day. Further on the formation of the QS complex in V3R-5R leads was of certain value. Combined assessment of ST segment elevation and the QS formation in the right precordial leads significantly increased diagnostic potentialities in the detection of right ventricular myocardial infarction.
