Selection of optimal channel for rate determination
First Claim
1. 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 plurality of ECG signals from a plurality of pairings of the plurality of electrodes;
a memory storing a configurable parameter indicating at least one preferred pairing of the plurality of pairings; and
at least one processor coupled to the sensor interface and the memory, the least one processor implementing a cardiac function analyzer to process the plurality of ECG signals to determine a plurality of signal interpretations of a physical condition of the patient, to detect a difference in the physical condition of the patient under two or more signal interpretations of the plurality of signal interpretations, and to resolve the difference by retrieving the configurable parameter and resolving the difference in favor of the at least one preferred pairing.

Abstract
According to at least one example, an ambulatory medical device is provided. The device includes a plurality of electrodes disposed at spaced apart positions about a patient'"'"'s body and a control unit. The control unit includes a sensor interface, a memory and a processor. The sensor interface is 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. The memory stores information indicating a preferred pairing, the preferred pairing being either the first pairing or the second pairing. The processor is coupled to the sensor interface and the memory and is configured to resolve conflicts between interpretations of first ECG signal and the second ECG signal in favor of the preferred pairing.
