EDV: LV End-Diastolic Volume (ml), ESV: LV End-Systolic Volume (ml), SV: LV Stroke Volume (ml), EF: LV Ejection Fraction (%), CO: Cardiac Output (ml/min), LVSP: LV End-Systolic Pressure (mmHg), LV dP/dtmax: the maximal rate of rise of LV Pressure according to time (mmHg/s), HR: Heart rate (beats/min), E: mitral early filling velocity (m/s), e´: early diastolic mitral annulus velocity by tissue Doppler imaging, E/e´: ratio of two velocities.
The values are averages ± standard deviation.
