Abstract :
Mathematical models of the ascending and descending parts of the pressure pulse contour in the ascending aorta were previously shown to be exponential functions of time (see A. Chatterjea and J. Njock Libii, Proc. 9th Ann. Conf. IEEE Eng. in Med. and Biol. Soc., vol.2, p.868, 1987). However, in that investigation the presence of incisura was neglected. Here, a mathematical model of the incisura is presented
