Claim:
1. A medical device comprising: a pressure input configured to be joined to a pressure sensor located proximate to a cardiac chamber of a heart, the pressure input receiving pressure measurements representative of a pressure in the cardiac chamber; an excitation source configured to deliver stimulation pulses to the heart at an initial pacing rate; a detector module to communicate with the pressure sensor, the detector module receiving and comparing the pressure measurements to a pressure threshold; and a processor adapted to instruct the excitation source to deliver the stimulation pulses at a pressure-based rate, higher than the initial pacing rate when the measured pressure exceeds the pressure threshold, the processor being further adapted to instruct the excitation source to cease delivery of the stimulation pulses at the pressure-based rate when the pressure measurements are no longer above the pressure threshold.
