A STUDY OF AORTIC PRESSURE CURVE DURING A CARDIAC CYCLE

摘要

An analysis of expected aortic pressure curve is discussed during a complete cardiac cycle. During this cardiac cycle, we study the aortic pressure curve for systolic phase when blood flows into aorta from the left ventricle on the assumption of inflow rate Q(t) to be A(1+ et), e , A > 0 with varying peripheral resistance Ro/( 1 + et), Ro being constant while for the diastolic phase, the pressure curve is analysed when blood flows out of aorta against a peripheral resistance that changes in response to baro-receptor stimulation. The expected aortic pressure curve is studied analytically and displayed graphically.
