Claim 12:
13. A method for a wearable cardiac defibrillator (WCD) system to work with an output device, the WCD system including a support structure configured to be worn by a patient, an external defibrillator configured to be coupled to the support structure and configured to defibrillate the patient while the support structure is worn by the patient, a motion sensor coupled to the support structure, and a timer, the method comprising:
defibrillating the patient while the support structure is worn by the patient;
generating, by the motion sensor, motion event data;
determining a duration of an inert period during which a motion statistic of the motion event data is less than a motion threshold;
determining whether the duration of the inert period exceeds an inert threshold; and
in response to a determination that the duration of the inert period exceeded the inert threshold, causing the output device to output a human-perceptible alert.
