1. A wearable medical device configured to monitor a patient for cardiac arrhythmias, comprising:
a water-resistant belt configured to be worn by the patient;
a plurality of ECG sensing electrodes configured to sense an ECG of the patient;
a plurality of therapy electrodes discrete from the plurality of ECG sensing electrodes and configured to provide at least one defibrillating shock to a body of the patient,
wherein at least some of the plurality of ECG sensing electrodes and the plurality of therapy electrodes are disposed on one or more common adhesive backings configured to be adhesively attached to the patient's torso;
an elongated cable comprising a removable connector; and
a control unit configured to be removably electrically coupled to the plurality of ECG sensing electrodes and the plurality of therapy electrodes via the removable connector of the elongated cable, configured to
monitor the sensed ECG of the patient, and
responsive to a detection of cardiac arrhythmia of the patient, provide at least one defibrillating pulse of energy to at least one of the plurality of therapy electrodes,
wherein the control unit is housed in a waterproof case formed from a waterproof material that is sealed to prevent ingress of water during operation of the wearable medical device in a wet environment.
