Abstract:
1. An ambulatory medical device, comprising: a plurality of electrodes configured to be disposed at spaced apart positions about a body of a patient; an electrode signal acquisition circuit having a plurality of inputs, each respective input of the plurality of inputs being electrically coupled to a respective electrode of the plurality of electrodes, the electrode signal acquisition circuit being configured to sense a respective signal provided by a plurality of different pairings of the plurality of electrodes; and a monitoring circuit, electrically coupled to an output of the electrode signal acquisition circuit, the monitoring circuit being configured to analyze the respective signal provided by each of the plurality of different pairings and to instruct the electrode signal acquisition circuit to select at least one of the plurality of different pairings to monitor based upon a quality of the respective signal provided by the selected at least one of the plurality of different pairings and a phase difference between the respective signal provided by the selected at least one of the plurality of different pairings and the respective signal provided by another selected at least one of the plurality of different pairings.
