Summary Coronary volume elasticity has been studied in the beating heart of the dog by introducing sinusoidal pressure oscillations in the aorta and by simultaneous measurement of phasic coronary inflow in the left circumflex branch. Coronary volume elasticity and coronary resistance are computed from the solution of the differential equation describing a linear elastic model. It was found by our method that the ratio of volume elasticity to peripheral resistance of the coronary system exceeds by a factor 2 to 3 the corresponding ratio computed for the total arterial system. Changes in coronary volume elasticity are directly related to changes in coronary peripheral resistance as measured under varying circulatory conditions.
