A detector (10) for sensing events in living tissue, containing a comparator (16) which compares an input signal corresponding to electrical signals from living tissue with a defined signal detection level, is described, an event being deemed to have occurred if the input signal exceeds the defined level of detection. More reliable detection of events is achieved when noise is present when a first integrator (14) generates the input signal by integrating electrical signals from the tissue, the comparator (16) then comparing the integrated signal with a level of detection for the integrated signal. <IMAGE> |
