Carotid‐femoral Pulse Wave Velocity*

Abstract

Simultaneous records of the pulse waves were obtained from the right common carotid artery and the right femoral artery by means of piezo-electric microphones in 26 per= sons whore ages ranged from 15 to 92 years. The time difference between the foot points of the waves from them two sites was termed Tar.A significant correlation was found between ToS and age, be= tween TOP and the systolic blood pressure and between Top and As described by Miller and White (1) and Geddes and Hoff (2), the pulse wave can be recorded by means of piezo-electric microphones placed externally above the artery. If T is the time difference between the foot points of two pulse waves recorded a t varying distances from the heart and D the length of the segment, the pulse wave velocity = D/T.

Arterial Compliance, Systolic Pressure and Heart Rate in Elderly Women at Rest and on Exercise

“…All that is required is the simultaneous recording of carotid and femoral pulse waves. Nielsen et al [19] have shown that the results from this method are comparable with those obtained by intra arterial measurement of PWV.…”

“…At Nielsen et al [ 19] have shown that PWV calculated from these measurements agrees well with direct mea surement of PWV by aortic catheterisation. Table I shows the means and standard er rors of the results obtained in the different tests.…”

“…To enable us to do this non-invasively, we estimated arterial compliance by measuring the pulse wave ve locity (PWV) down the aorta [11,19],…”

Noninvasive Assessment of Subclinical Atherosclerosis in Children and Adolescents

“…Elevated systolic blood pressure and pulse pressure play integral roles in cardiovascular outcomes such as left ventricular hypertrophy, ventricular failure, and the atherosclerotic process. Furthermore, systolic hypertension is a major risk factor for coronary heart disease, 143,144 stroke, 145 and cardiovascular 146 and total 147 mortality. Therefore, it is not surprising that measures of arterial stiffness also predict future cardiovascular risk in adults.…”

Effet de l'âge et de la compliance du circuit d'éjection sur les courbes de fonction cardiaque et les pressions systoliques du coeur isolé de rat

“…Dans quelle mesure cette altération est-elle compensée par la régulation de la fonction pompe apportée par le système nerveux autonome ? L'accroissement des pressions systoliques (PS) observé avec l'âge chez l'homme et l'animal [12,14] est-il la conséquence des modifications du myocarde, du circuit ou de la régulation nerveuse autonome?…”
