Abstract

The invention evaluates the mechanical condition of a heart in a patient (10) by noninvasively providing a pulse signal representative of arterial pulsation by placing a transducer (11) sufficiently close to the skin of the patient (10) to provide an electric signal representative of the arterial pulsation. The patient (10) is subjected to a heart-straining maneuver to provide an arterial pulse contour squarewave signal during the heart-straining maneuver having an early strain phase amplitude at the beginning of the heart-straining maneuver and a later strain amplitude at the end of the heart-straining maneuver. An indication is provided of the ratio of the late strain phase amplitude which ratio is representative of the mechanical condition of the heart of the patient (10).
The invention may also provide an indication of the relationship between that ratio and the pulmonary capillary wedge pressure of the patient (10). The invention may also provide an indication of the state of the hydration of the patient (10).
