ABSTRACT:
In an implantable medical device for stimulating a heart, an activity signal from an activity sensor is transformed by response amplification into a stimulation rate at which a stimulation pulse generator delivers stimulating pulses to the heart. The response amplification is automatically optimized because the device contains an evaluation stage which, over a period of time, registers the stimulation rate and then compares this rate to a preset average rate, whereupon a control unit in changes the response amplification so the response amplification is increased when the registered stimulation rate is slower than the average rate and is decreased when the registered stimulation rate is faster than the average rate.
