Abstract
A medical device implantable into the body of a patient with which spontaneous tissue contractions can be detected and tissue contractions can be stimulated, generates a stimulation after the expiration of an adjustable first time interval, started by the respective detection or the stimulation of a tissue contraction, if a spontaneous tissue contraction is not detected before the expiration of the first time interval and if a shorter, second time interval, started by the detection or stimulation of a tissue contraction, has not yet expired. Detection of a spontaneous tissue contraction during the second time interval starts a new second time interval. The duration of the second time interval is automatically set such that it is always shorter by a defined amount than the duration of the first time interval.
