Abstract
A system and method for detection of specific cardiac depolarization events, such as atrial and ventricular beats. Cardiac electrical activity is sensed to generate a sense signal that is decomposed into components by orthogonal filters. Statistical features are extracted from the components and analyzed to detect a specific event. In one embodiment, the sense signal is decomposed into frequency components by bandpass filtering. The design of the bandpass filters is such that the frequency components can be analyzed to determine whether they match the frequency components of a template signal corresponding to the specific cardiac depolarization event.
