Patent ID: 8897860

Claim:
An ambulatory medical device, comprising: a plurality of electrodes disposed at spaced apart positions about a patient's body; and a control unit including: a sensor interface coupled to the plurality of electrodes and configured to receive a first ECG signal from a first pairing of the plurality of electrodes and to receive a second ECG signal from a second pairing of the plurality of electrodes; a memory storing a configurable parameter indicating a preferred pairing, the preferred pairing being either the first pairing or the second pairing; and a processor coupled to the sensor interface and the memory, the processor comprising a cardiac function analyzer to process the first ECG signal to determine a first ECG signal interpretation of a physical condition of the patient, to process the second ECG signal to determine a second ECG signal interpretation of the physical condition of the patient, to detect a conflict between ECG signal interpretations wherein the conflict comprises a difference in the physical condition of the patient under the first ECG signal interpretation and the second ECG signal interpretation, and to resolve the conflict by retrieving the preferred pairing from the configurable parameter stored in the memory and resolving the conflict in favor of the preferred pairing.
