The purpose of this study was to determine the magnitude of arterial capacitance in human by no-ninvasive method.

In 60 patients (Age : 62.1±13.4 years) without cardiovascular disease first-pass radionuclide angio-graphy was performed using a digital gamma ca-mera to calculate cardiac output and stroke volume (SV). Systolic interval (ts), diastolic interval (td) and arterial blood pressure were measured using ECG, phonocardiography and sphygmomanometer.

We assumed a simple model in which all capa-citance (C) lumped into one site with a resistance (R) in parallel to the C. C was calculated by the following basic equations.
