Wearable ambulatory medical device with multiple sensing electrodes

摘要: An ambulatory medical device including a plurality of electrodes configured to be disposed at spaced apart positions about patient's body, an electrode signal acquisition circuit, and monitoring circuit. The circuit has inputs each electrically coupled respective the is sense provided by different pairings electrodes. output analyze instruct select least one monitor based on quality signal, phase difference between that other pairings, position relative criteria.
