Key words: myocardial infarction, ECG diagnosis.

 During research are learnt 107 patients. In 20 cases (18,7%) was founded common infarct of right and left ventricle. From 20 ECG eighteen (90%) shown elevation of ST segment at pectoral right pericardial leads, in 2 (10%) ST is depressing, that was estimated as sub-endocardial infarction at right ventricle.

A QRS complex change by QS kind V3R-V6R branches has made 65% (13 EKG), in V3R-V4R 5% (1 ECG). Its change by kind of QS happened at 1 ECG (5%) V4R-V6R, but in 3 (15%) at V6R, where parallel V3R-V5R we had RS (15%). But at 1 (5%) ECG was presented V3R-V6R field rSr. We received Qr 1 (5%) in case of V4R-V6R field, where V3R was settled as rSR.

At 14 ECG (70%) was revealed negative T – kinks, 4 (20%) positive, but at 4 (10%) - izoelectrical.

So, according to the research we can say: in case of left ventricle back-lower infarct, it is necessary to register ECG at the right prekardial branches for duly diagnostics of right ventricle dysfunction. The distribution of infarct zone on the right ventricle is best observed with the help of V3R-V4R branchs. At the right thorax branchs elevation of ST segment, QRS complex change and negative T – kinks, we can view as index- criterions of right ventricle infarct. QRS change QS or Qr kind no less then 3 branchs (V4R-V5R or V4R-V6R), also shows the necrosis of the right ventricle.
