Abstract
A heart stimulator has a pulse generator which emits stimulation pulses for delivery to the heart of a patient through a lead connected to the pulse generator and introduced into the heart. The heart stimulator has an evoked response detector which includes a measuring unit for measuring electrode signals picked up by the lead. An averaging unit is supplied with the electrode signals and forms an average value of the amplitude of the respective electrode signals for each heartbeat. A comparator in the evoked response detector compares the average value for each heartbeat with two predetermined limit values and emits a signal indicating that the electrode signal results from a fusion beat if the average values are between the two limit values.
