  • Abstract
  • Look Inside

Finger and toe pulse waves were simultaneously recorded in medical students and outpatient hyperten-sive patients. The delay of the rise of toe pulse to that of finger pulse (t) was almost halved in students on postural change from the supine position to the sitting position. This was mainly due to an increase in the pulse wave velocity in the aorta, which was thought to be induced by the increase in hydrostatic pressure in the aorta. In students a marked dicrotic wave was obser-ved in both finger and toe pulse waves.
