ABSTRACT:
An apparatus for determining a physical condition in a living subject by determining peripheral resistance to flow is wherein peripheral resistance to flow is determined by measuring changes in the pressure drop characteristic in an artery during diastole. The pressure drop characteristic can be determined by measuring absolute pressure, relative pressure or dimensional changes in the artery during diastole. The apparatus can advantageously be used in a rate-responsive heart stimulator.
