1. A wearable cardioverter defibrillator (WCD), comprising:
a support structure configured to be worn by a patient;
an energy storage module configured to store an electrical charge;
a discharge circuit coupled to the energy storage module;
one or more electrodes configured to render an electrocardiogram (ECG) signal of the patient while the patient is wearing the support structure;
a user interface configured to output an alarm in response to a shock alert signal;
a motion sensor configured to output a signal while the patient is wearing the support structure; and
a processor configured to:
receive the signal from the motion sensor,
determine, using the signal received from the motion sensor, one of a position of the patient, a movement of the patient, or both the position and the movement of the patient,
receive the ECG signal,
determine, from the ECG signal, whether a shock criterion is met,
cause the user interface to generate the shock alert signal based on the shock criterion,
determine a response time period based on one of the position of the patient, the movement of the patient, or both the position and the movement of the patient,
control the discharge circuit to discharge the stored electrical charge when the response time period has elapsed and a user input has not been received at the user interface, and
control the discharge circuit to not discharge the stored electrical charge when the user input has been received at the user interface prior to the response time elapsing.
