Abstract
An in vivo method of determining the conductivity of a liquid such as human blood, including the steps of determining a location in a ventricle of a patient's heart at which blood conductivity may be measured effectively, positioning a catheter having a plurality of spaced electrodes in the ventricle such that at least a pair of adjacent electrodes are positioned at the location, applying a current of known magnitude to the adjacent electrodes, measuring the voltage between the adjacent electrodes, and determining the conductivity of the patient's blood from the known current and measured voltage.
