An event detector, useful, for example, in pacemaker technology, detects signal portions which have characteristic events exceeding a certain established threshold. An optimal setting of the detector sensitivity is achieved by passing the input signal through a circuit which measures the signal's maximal values, then establishes the difference between the maximal values and the established threshold, and, in a preferred embodiment, controls the threshold in accordance with the difference and a given desired threshold value. The desired threshold value can be based on, for example, difference histograms or trend data. The event detector can be designed to respond to a variety of signal parameters, such as amplitude and/or slope.
