from doppler mitral flow velocity profiles , the percent of lv filling due to atrial systole ( percent atrial contribution ) and at one-third of diastole ( one-third filling fraction ) , the peak filling rate and the peak filling rate normalized for lv end-diastolic volume and the time from mitral valve opening to peak early velocity and from aortic valve closure to peak early velocity were determined .
