SEMI-QUANTITATIVE ANALYSIS OF CAROTID ARTERIAL WAVE FORM – ITS PHYSIOLOGICAL CHANGES WITH AGING IN NORMAL SUBJECTS
Materials: One-hundred and eighty-seven normal subjects were selected and classified into 5 groups according to their age. Method: Carotid arterial pulse wave was obtained from each individual and various calculations were made in terms of its timing and amplitude. Results and comments: As the age advanced, the following changes were found; decrease in amplitude of the percussion wave, increase in height of the tidal wave, increase in level of the dicrotic notch, indistinction of the dicrotic wave and widening in degree of the percussion to the tidal wave. These physiological alterations with aging process may be of value as bacic data when evaluating abnormal morphology to be found in hypertension or arteriosclerosis which being prepared.
