Left ventricular diastolic filling in XXXX .

@entity1 @entity340 @entity64 @entity472
The pattern of left ventricular diastolic filling in @entity1 with @entity340 ( @entity472 ) as assessed by gated blood pool scintigraphy has received little attention. Twenty-one normal @entity1 (group 1), 24 @entity1 with significant @entity472 and ejection fractions of 50% or more (group 2) and 15 @entity1 with significant @entity472 and ejection fractions less than 50% (group 3) were studied. From the time-activity curve, the peak filling rate and mean filling rate (as end-diastolic volumes [EDV]/s) and percent @entity64 volume filled at first third of diastole and at the end of the rapid filling period were determined. Group 2 had a reduced peak filling rate (2.58 +/- 0.65 EDV/s, p less than 0.05) compared with group 1 (3.11 +/- 0.65 EDV/s). Similarly, the percent @entity64 volume filled at the end of the rapid filling period was reduced in group 2. Group 3 @entity1 had a lower peak filling rate and mean filling rate than group 1 @entity1 . However, percent @entity64 volume filled at first third of diastole and percent @entity64 volume filled at the end of the rapid filling period were greater in group 3 than in group 1. Two distinct patterns of diastolic filling were noted in @entity1 with @entity472 . Group 2 @entity1 had reduced peak filling rates with less diastolic filling during the rapid filling period. Although the peak filling rate was reduced in group 3, more complete filling occurred during the rapid filling period.
