Abstract
Passive head-up tilt(HUT) has been used to diagnose the idiopathic syncope which is transient loss of consciousness due to cardiovascular intolerance in upright without any organic disease. This study was carried out to investigate whether the cardiovascular intolerance occurred in the HUT following supine position of relatively short period in 10 healthy young men. No syncope occurred at control HUT following 30 minute supine position. But five of ten subjects complained syncope or presyncopal symptoms(S group) at the HUT following 3 hour supine position. In the rest non-syncopal subjects(NS group), hemodynamic parameters showed the changes as same as the control HUT. In S group, mean arterial pressure decreased whereas it increased in NS group and other hemodynamic parameters showed the greater amount of changes than NS group. This results indicate that the postural hypotension could develope when we take a sudden upright position following a few hours of supine rest even though no experience of syncope ordinarily. It seems that this hypotension is mainly based on greater blood pooling in lower extremities during the upright position, and the secretion of epinephrine facilitates the process of syncope.
