Claim Text:
1. A method of regulating the operation of an implanted cardiac stimulation device, comprising: receiving signals from both an implanted hemodynamic sensor and of intracardiac electrograms by a processor; determining systolic pressure from the implanted hemodynamic sensor; integrating the received signals from the hemodynamic sensor and the intracardiac electrograms by the processor; detecting systolic and diastolic phases of each heartbeat using said signals; and generating conditioned pulsing stimuli by a pulse generator configured to prevent inappropriate cardiac pacing beat after beat, wherein said generating conditioned pulsing stimuli comprises producing a digital systolic pressure wave, from one heartbeat to the next, with a logic “1” level during the systolic phase and a logic “0” level during the diastolic phase based on a threshold value of the systolic pressure to distinguish between the systolic phase and the diastolic phase during each heartbeat in order to prevent ventricle pacing during a logic “1” level of the digital wave, thereby preventing inappropriate cardiac pacing beat after beat.
