  • Patent number: 11167145
    Abstract: A system for monitoring and evaluating the ventricular contractility of a heart muscle includes a device for electrically stimulating the heart muscle of a patient, and an extracorporeal blood pressure sensor. A record, responsive to stimulated ventricular contractions, is created by the pressure sensor. The response record is then evaluated to identify a pressure/time, rate-change in arterial pressure (dp/dt) that results within the time duration of a ventricular contraction in a cardiac cycle. In turn, dp/dt is evaluated as an indicator of ventricular contractility and the health of the patient's heart muscle.
