Determination of arterial impedance by non-invasive measurements.
Most studies dealing with the arterial system impedance as resistance to blood ejection from the left ventricle are based on catheterization examinations of the aorta and the great arteries. The present work shows the possibility of using non-invasive approaches and describes one of them consisting in non-invasive determination of arterial impedance by measuring arterial pressure, cardiac output and the cardiac cycle phase structure. The results are compared with those of other studies.
