Zusammenfassung:FIELD: medicine. SUBSTANCE: method involves determining left ventricle stroke volume. Left ventricle myocardium mass is calculated. Specific ejection index is calculated from formula P=Y/X, where P is the specific ejection index, in units, Y is the left ventricle stroke volume, in ml and X is the left ventricle myocardium mass calculated by means of Teiholz formula, in g. P being found greater than 0.8, left ventricle myocardium operation efficiency is considered to be high. The value being enclosed between 0.6 and 0.8, operation efficiency is considered to be moderate. The value being below 0.6, efficiency is low. EFFECT: high accuracy of diagnosis; enhanced effectiveness in evaluating myocardium hypertrophy treatment results.
