Abstract
Device for maintaining or restoring a natural heart rhythm through the generation of an electrical stimulation signal, in particular in the form of an implantable heart pacemaker, which device shows two sensors arranged inside the body of the patient for picking up a body-specific signal that contains information concerning the demand for heart performance or another magnitude relevant to the heart. Connected to the downstream side of the sensors is a processing unit that obtains, from the temporal difference of a body-specific signal received one after another at both sensors, a body-specific time-delay signal, which represents the length of the determined time delay. The body-specific time-delay signal forms at least indirectly a control signal that influences the point in time and/or the time sequence of the stimulation signal.
