Selection of optimal channel for rate determination
First Claim
1. A medical device comprising:
- at least one sensing electrode configured to be disposed on a patient; and
a control unit comprising;
a sensor interface coupled to the at least one sensing electrode and configured to receive at least one electrocardiogram (ECG) signal from the at least one sensing electrode;
a memory storing a configurable parameter indicating at least one preferred heart rate detection method; and
at least one processor coupled to the sensor interface and the memory, the least one processor being configured to implement a cardiac function analyzerto process the at least one ECG signal to determine a heart rate of the patient using two or more heart rate detection methods,to identify a difference in the heart rate of the patient as determined by the two or more heart rate detection methods,to retrieve the configurable parameter,to resolve the difference in favor of the at least one preferred heart rate detection method,to detect a potential arrhythmia based on the heart rate, andto initiate treatment in response to detecting the potential arrhythmia.

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.
