A pacemaker comprises an interference detecting circuit (2), and an evaluating and storing means (4) for continuously evaluating and storing the heart rate. The evaluating and storing means is adapted to store the rate evaluated from at least one of the latest cardiac cycles free of interference. A determining means (8) is provided for determining an interference backup rate from the stored rate in response to the detection of the onset of an interference situation. A control means (9) is provided to then adjust the pacing rate equal to said interference backup rate. <IMAGE>
