<p>A system for and method of treating a malfunctioning heart based on hemodynamics, the pressure at a site in a patient's circulatory system being sensed. A signal representative of short term mean pressure at a site in the circulatory system over a period of given duration is developed by an RC circuit (50, 51, 52). A signal representative of baseline pressure, which may be a varying long term mean pressure at the site is developed by an RC circuit (46, 47, 48). Alternatively, a signal representing a selected fixed baseline pressure may be supplied from a potentiometer (100). If the short term current mean pressure differs from the baseline pressure by a predetermined amount, an indication of hemodynamic compromise, cardioversion/defibrillation is effected (FIG. 10).</p> |
