ABSTRACT:
A system for and method of treating a malfunctioning heart is based on hemodynamics, the pressure at a site in a patient's circulatory system being sensed. A signal is developed representative of short term mean arterial pressure (MAP), mean right atrial pressure (MRAP), mean right ventricle pressure (MRVP), mean left atrial pressure (MLAP), mean left ventrical pressure (MLVP) or mean central venous pressure (MCVP). A signal representative of fixed baseline pressure is provided and if the short term current mean pressure differs therefrom by a predetermined value, an indication of hemodynamic compromise, cardioversion/defibrillation is effected. In a second embodiment, the determination of whether the difference between fixed baseline pressure and mean current pressure is undertaken after a rate criteria (for example a heart rate above 155 b.p.m.) has been met. In a third embodiment, the rate and pressure criteria both must exist at the same time, before cardioverting/difibrillation is initiated. In a fourth embodiment, a microprocessor is used. The system may be integrated with antitachycardia and/or antibradycardia pacemakers.
