1. An ambulatory medical device configured for multiple operating modes, comprising:
a plurality of ECG sensing electrodes for sensing ECG signals of a patient;
a data storage having stored therein one or more arrhythmia detection parameters;
at least one processor that is coupled with the plurality of ECG sensing electrodes and that is configured to detect a cardiac arrhythmia condition indicated by the ECG signals based on the one or more arrhythmia detection parameters;
a plurality of therapy electrodes configured to deliver a treatment to the patient in response to detection of the cardiac arrhythmia condition indicated by the ECG signals; and
a moisture sensor configured to detect moisture content in an environment of the patient,
wherein the at least one processor is also coupled with the moisture sensor and the plurality of therapy electrodes, and
wherein the at least one processor is also configured to
in a default operating mode, deliver the treatment to the patient based on the one or more arrhythmia detection parameters in response to detection of the cardiac arrhythmia condition,
change from operating in the default operating mode to operating in a water operating mode based on the detected moisture content transgressing a predetermined threshold value, and
in the water operating mode, change the one or more arrhythmia detection parameters relative to the default operating mode.
