Post extrasystolic potentiation stimulation with physiologic sensor feedback

摘要: A Post-Extrasystolic Potentiation (PESP) cardiac pacing energy stimulator for applying paired and/or triggered stimulation pulses to the right atrium ventricle incorporating one or more sensors, such as a venous oxygen saturation, ventricular, atrial, arterial blood pressure, intracardiac systemic flow sensor, and signal processing circuitry controlling frequency of number heart cycles between periodic delivery induce PESP treatment congestive failure other dysfunctions. Preferably, first e.g., ventricular pressure is employed monitor performance heart, develop index (CPI) second an saturation sensor positioned in coronary sinus, muscle stress (CSI) balance stress. The may be incorporated into dual chamber (DDD) system with without physiologic rate control backup cardioversion/defibrillation therapy capabilities separate, single purpose device. has particular application atrial augmenting filling ventricles.
