This paper aims to elicit the BCVI as a non-invasive, unobstructive method for the evaluation of cardiovascular hemodynamic indices, at the brachial (upper arm) level. A coupled mathematical model of the brachial hemodynamic flow and the electrical field, where the electrical conductivity of the arterial blood that depends on the flow characteristics is a key element, is formulated and solved numerically. Numerical simulation results suggest that BCVI information may be correlated with and used to complement the ECG and pulsometry measurements in providing a more comprehensive picture of the local and general cardio-vascular state of health.
