Abstract
Abstract A method for finding rate responsive parameter settings in a functional relationship between sensor signal and stimulation frequency for a pacemaker by selecting desired heart rates optimal for a patient with respect to certain work loads. The respectively corresponding sensor signal values are obtained from the sensor, and the parameters are calculated by inserting the sensor signal values and selected frequencies into the functional relationship.

Claim 1
Independent Claim
120 words
A method for finding the parameters in a functional relationship between the stimulation frequency of an implantable physiological stimulating device, in particular a heart pacemaker, and a sensor signal indicative of the physical load condition of a patient, characterized by the following steps: a) selecting a first stimulation frequency in substantial correspondence with a first load condition b) obtaining a first sensor signal corresponding to said first load condition c) repeating, steps a) - b) for further load conditions corresponding in number to the number of said parameters, and resulting in further stimulating frequencies and sensor signals respectively corresponding to said further load conditions d) calculating the parameters from said functional relationship and said selected frequencies and obtained sensor signals.
