[Information value of right precordial ECG leads in the diagnosis of right ventricular myocardial infarct]. / Informativnost' pravykh prekardial'nykh otvedenii EKG v diagnostike infarkta miokarda pravogo zheludochka.

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.

[Correlation of the indices of phase structure of left ventricular systole in patients with isolated left ventricular and combined biventricular myocardial infarction]. / Sopostavlenie pokazatelei fazovoi struktury sistoly levogo zheludochka u bol'nykh s izolirovannym levozheludochkovym i sochetannym biventrikuliarnym infarktom miokarda.

The correlation of indices of the phase structure of the left ventricular systole in patients with isolated left ventricular (140 patients) and combined biventricular (60 patients) myocardial infarction showed prolonged tension time resulting from isometric contraction, and a great difference between the actual and proper systolic values in the affection of both ventricles irrespective of the outcome of disease. In low sensitivity of indices of the phase analysis of the left ventricular systole the following indices proved to be specific and informative for recognition of the right ventricle involvement: a period of isometric contraction, duration of the common systole, difference between the actual and proper systolic values, and tension time.

[Clinical, morphological and pathogenetic characteristics of combined myocardial infarct of the right and left ventricles]. / Nekotorye osobennosti kliniki, morfologii i patogeneza sochetannogo infarkta miokarda pravogo i levogo zheludochkov.

Proceeding from clinicomorphological correlations in 63 patients with combined right and left ventricular myocardial infarction and in 92 patients with isolated left ventricular myocardial infarction some features of heart coronary pathology that contributed to the formation of a process of different site in the right and left ventricles were revealed. A hypothesis of variants of the pathogenesis of myocardial infarction of the anterior and posterior free walls of the right ventricle was discussed.

[Rupture of the interventricular septum associated with myocardial infarction of the left and right ventricles]. / Razryv mezhzheludochkovoi peregorodki v sochetanii s infarktom miokarda levogo i pravogo zheludochkov.

Based on observation over 7 patients with interventricular septum rupture associated with myocardial infarction of the left and right ventricles the authors assume a pathogenetic relationship between interventricular septum rupture and right ventricle involvement into the process. The dependence between the disease prognosis and right ventricle function is discussed.

[During life diagnosis of myocardial infarction with involvement of the right ventricle]. / Prizhizennaia diagnostika infarkta miokarda s vovlecheniem pravogo zheludoohka.

The right segments of the heart and pulmonary artery were catheterized and pressure in them measured in 113 patients with acute transmural and macrofocal myocardial infarction. Increased end diastolic pressure in the right ventricle (EDPRV) was over 10 mm Hg and more frequently encountered in antero-inferior (in 70%) and inferior (in 31.5%) localization of myocardial infarction (p less than 0.05) which is due, as the authors believe, to the concomitant lesion of the right ventricle. Several possible haemodynamic variants of concomitant lesions of the right and left ventricles are described. A number of autopsy studies are given confirming that enhanced EDPRV in normal or moderately raised end diastolic pressure in the pulmonary artery points to the involvement of the right ventricle. At the same time only in a part of patients the clinical and ECG data alone suggested involvement of the right ventricle.
