Pressure dependence of the canine aortic characteristic impedance and the effects of alterations in smooth muscle activity


Experiments were performed on anaesthetised dogs to separate the effects of changes in aortic smooth muscle activity on the characteristic impedance Zc from its passive pressure dependence. Zc was measured from the ascending aortic pressure/flow relationship in a wide pressure range caused by forced slow oscillations in pressure induced with an external… (More)
