Finger and toe pulse waves were simultaneously recorded in medical students and outpatient hypertensive 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 observed in both finger and toe pulse waves. That the interval between the main and dicrotic waves (T) was shorter for finger pulse than toe pulse also seems to be ascribable to the influence of the intraaortic pressure: Pulse was transmitted faster in the systolic phase than in the diastolic phase. The features of pulse waves of hypertensive patients were that (t) was short even in the supine position, and that dicrotic wave was small or absent especially for toe pulse. These differences were considered to be accounted for by the high blood pressure and the structural change of arterial wall in the hypertensive patients.
在医学生和门诊高血压患者中同时记录手指和脚趾脉搏波。从仰卧位变为坐位时，医学生脚趾脉搏上升相对于手指脉搏上升的延迟时间（t）几乎减半。这主要是由于主动脉中脉搏波速度增加，这被认为是由主动脉中静水压力增加所引起的。在医学生中，在手指和脚趾脉搏波中均观察到明显的重搏波。手指脉搏主波和重搏波之间的间隔（T）比脚趾脉搏短，这似乎也归因于主动脉内压力的影响：脉搏在收缩期比舒张期传播得更快。高血压患者脉搏波的特征是，即使在仰卧位时（t）也较短，并且重搏波较小或不存在，尤其是在脚趾脉搏中。这些差异被认为是由高血压患者的高血压和动脉壁结构变化所导致的。
