EVOKE RESPONSE DETECTOR, AVERAGING THE VALUE OF THE AMPLITUDE OF THE PICKED UP ELECTRODE SIGNAL

摘要

An evoked response detector for a heart stimulator, which comprises a pulse generator (2) for producing stimulation pulses for delivery to the heart (8) of a patient through a lead (6) intended to be connected to the pulse generator and introduced into the heart, comprises measuring means (10) for measuring electrode signals picked up by the lead. An averaging means (16) is provided to form an average value of the amplitude of the picked up electrode signal for each heart beat, and a comparison means (12) is arranged to determine whether a picked up electrode signal results from a fusion beat or not by comparing the average value with predetermined limit values.
