Implantable cardiac stimulation device and method for optimizing sensing performance during rate adaptive bradycardia pacing
An implantable cardiac stimulation device including a ventricular defibrillator and a rate adaptive cardiac pacer automatically adjusts post-pacing sensing parameters dependent upon pacing rate. The device includes a pulse generator that applies stimulation pulses to a heart at a calculated variable stimulation rate as a function of physiologic demand. A sensing circuit senses ventricular activity of the heart responsive to a plurality of sensing parameters including post-pace sensing parameters and a processor adjusts the post-pace sensing parameters responsive to the selected pacing rate.
