  • Abstract
  • Look Inside

The transmission delays of the upstroke and the incisura of the aortic and the pulmonary pulses in 20 normal subjects were measured by dual micro-tipcatheter. In aorta, the mean delay of the incisura was 14.9 msec while that of the upstroke was 19.3 msec (p<0.005). This difference was greater with aging. But in pulmonary artery, they were almost same. The results were explained by vascular com-pliance.

Then we concluded that it was useful for apprecia-tion of arteriosclerosis to measure the transmission delays of different portions of the arterial pulse.
