METHOD FOR DETERMINING BASIC FUNCTIONAL HEMODYNAMIC FEATURES OF THE LEFT VENTRICLE OF THE HEART Russian patent published in 1998 - IPC

FIELD: medicine. SUBSTANCE: method involves recording electrocardiogram, measuring QR, RS, QRS, ST-T, R-R interval durations without blocking His bundle limbs. P₁P₂ duration is additionally measured under blocked left limb of His bundle. S₁S₂ duration is measured under blocked right limb of His bundle. Main functional and volume hemodynamic characteristics of the left ventricle of the heart are calculated in cases of sinus, supraventicular and ventricular cardiac rhythms in rest state and under dynamic loading carried out according to original mathematical formulas. EFFECT: enhanced accuracy of method. 20 dwg , 9 tbl
