Abstract

See full text

A method and apparatus for automatically adjusting the sensing threshold of cardiac rhythm management devices. The invention is particularly suited for implementation in devices such as implantable cardiac pacemakers and implantable cardioverter/defibrillators. A method and apparatus are provided in which a noise level and signal level for a sensing channel are determined for each cardiac cycle with the sensing threshold of the channel being adjusted in accordance therewith.
