　To assess the left ventricular (LV) filling dynamics during atrial systole, A/D ratio (amplitude of atrial contraction wave / amplitude of early diastolic wave) of LV inflow velocity pattern recorded by pulsed Doppler echocardiography, A/H ratio of apexcardiogram, the amplitude of the atrial component of LV pressure (ΔPa) and left ventricular end-diastolic pressure (LVEDP) were analyzed in 72 patients with various heart diseases.
　There was a significant correlation between LVEDP and A/D ratio in patients with the LVEDP of less than 20 mmHg (r=0.71, pΔPa (r=0.78, p　In conclusion, combined analysis of A/D ratio of LV inflow velocity pattern and A/H ratio of apexcardiogram may be useful for the evaluation of the LV filling dynamics during atrial systole in various heart diseases.
