Abstract
Computer-generated "realistic" structures of arterial trees consisting of 8000 segments have been used as a basis for computer simulations of coronary hemodynamics. For the perfusion pressure, a synthesized wave form typical of the aortic pressure was used, while the temporally varying intramyocar- dial pressure was related to the (also) synthesized left ventricular pressure. The elastic properties of the vessel segments were derived from a simple ad- hoc model of arterial compliance. The model yields the typical wave form of pulsatile coronary flow. The variability of coronary flow patterns resulting from variations in the way intramyocardial squeezing is applied has been investigated in detail. 1 Introduction The wave form of corona
