Wearable ambulatory medical device with multiple sensing electrodes
First Claim
1. An ambulatory medical device, comprising:
- a plurality of sensing electrodes configured to be disposed at spaced apart positions about a body of a patient;
one or more therapy electrodes configured to be disposed about the body of the 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 sensing electrode of the plurality of sensing electrodes, the electrode signal acquisition circuit being configured to sense a respective signal provided by each of a plurality of different pairings of the plurality of sensing electrodes; and
a monitoring and detection circuit, electrically coupled to an output of the electrode signal acquisition circuit, the monitoring and detection circuit including at least one processor configured to analyze the respective signal provided by each of the plurality of different pairings, instruct the electrode signal acquisition circuit to select at least one of the plurality of different pairings to monitor based upon at least a quality of the respective signal provided by the selected at least one of the plurality of different pairings, analyze the respective signal provided by the selected at least one of the plurality of different pairings, and initiate a therapy to the patient via the one or more therapy electrodes on the basis of the analysis.

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