Abstract

An implantable medical device system and associated method select subcutaneous sensing electrodes for use in monitoring the heart rhythm. A subset of multiple sensing vectors is selected from a number of electrodes positioned at a first subcutaneous location and one electrode positioned at a second subcutaneous location. The subset of sensing vectors includes one vector that includes the electrode positioned at the second location. A signal quality parameter corresponding to each of the sensing vectors of the subset is determined.
