Abstract
A detector for sensing events in living tissue, such as electrical events in a heart, contains a microprocessor functioning as comparator which compares an input signal corresponding to electrical signals from the living tissue with a defined signal detection level, and an event is deemed to have occurred if the input signal exceeds the defined detection level. More reliable detection of events in the presence of noise is achieved by also providing an integrator which generates the input signal to the comparator by integrating electrical signals obtained from the tissue, the comparator then comparing the integrated signal with a detection level selected for use with the integrated signal.
