Claim 11:
12. A wearable monitoring device, comprising:
at least two ECG channels corresponding to a plurality of pairings of ECG sensing electrodes disposed at different axial positions around a body of a patient and integrated into a garment such as a shirt or vest that is worn on a torso of the patient;
a signal acquisition circuit configured to be integrated into the garment, the signal acquisition circuit being configured to be electrically coupled to the ECG sensing electrodes and configured to process ECG signals; and
a processor in communication with the signal acquisition circuit, the processor being configured to
instruct the signal acquisition circuit to analyze respective signals provided by a first one of the at least two ECG channels,
determine a presence of an arrhythmia condition based on the respective signals from the first one of the at least two ECG channels,
determine an initial confidence level in the determined arrhythmia condition,
select a second one of the at least two ECG channels,
assess an updated confidence level in the determined arrhythmia condition based on respective signals from the second one of the at least two ECG channels, by
increasing the initial confidence level in the determined arrhythmia condition in response to determining that the arrhythmia condition is still present or is also present on the second ECG channel, or
decreasing the initial confidence level in the determined arrhythmia condition in response to determining that the arrhythmia condition is not present or is no longer present on the second ECG channel, and

execute one or more instructions that result in defibrillation being applied to the body of the patient in response to the updated confidence level being above a certain threshold.
