Abstract/OtherAbstract:
Within-subject blood pressure (BP) variability was studied in the context of orthostatic testing. Nineteen healthy men volunteered for biweekly orthostatic testing. BP's were taken on alternate minutes during 5 min of supine rest and a subsequent 5 min of quiet standing. Within-subject variance was computed for systole and diastole by protocol condition; respective variances were than pooled (i.e. averaged) across subjects. The within-subject estimate of variance for a single BP reading in either position was approximately 6 torr (i.e. 1 S.D.). This variance estimate was reduced by averaging additional BP readings from the same visit, and more so by averaging BP readings from multiple visits. These findings have use in the design of orthostatic protocols and in the interpretation of BP data derived therefrom.
