We evaluated the accuracy of the recently reported technique of estimating intraventricular volume by measurement of intracavitary electrical conductance in six isolated, ejecting, canine left ventricles. Left ventricular volumes were measured directly by a previously validated servosystem that employed an electroconductive balloon placed in the left ventricular cavity. The volume measured continuously by the balloon method (Vbal) was compared with that estimated by the conductance method… CONTINUE READING
