Femoral artery catheterization (FAC) may be expected to produce changes in peripheral blood flow dynamics. We recently developed a computer assisted admittance plethysmograph (CAAP) to


compute forearm and calf pulse volume (V), peak net inflow (F), and pulse transit time (PT), i.e. QRS-peak net inflow. Bilateral calf plethysmograms were obtained in 14 males (60±6y)


undergoing coronary angiography. When compared to healthy younger normals (n=8,26±4y), these patients had reduced baseline values of V(39.8%,p
