ABSTRACT:
The invention shows a heart output and circulatory impedance measuring med and associated apparatus based on consecutive subtraction and synchronous summation of digitized ventriculographic images which effectively distinguishes between the motion resulting from contraction of the heart, and the motion resulting from actual displacement or physical movement of the heart back and forth within the chest cavity. From these data is computed a decrement in ventricular volume yielding, in time with subsequent images, the amount of blood ejected from the ventricle that represents the flow. By simultaneously recording the ventricular pressure and by synchronously dividing the pressure by the flow, ventricular load impedance is obtained.
