1. A wearable cardioverter defibrillator (“

  • WCD”

    ) system, comprising;

    a support structure configured to be worn by a patient;

    a power source;

    an energy storage module configured to be charged from the power source so as to store an electrical charge;

    a discharge circuit;

    one or more transducers configured to render a plurality of physiological inputs from one or more patient parameters that are sensed from different parts of the patient'"'"'s body; and

    a processor configured to;

    determine a plurality of individual analysis scores from the physiological inputs,determine an aggregate analysis score from a plurality of the individual analysis scores,determine whether or not the aggregate analysis score meets an aggregate shock criterion, andresponsive to determining that the aggregate shock criterion is met, control the discharge circuit to discharge the stored electrical charge through the patient within 5 min from when it is determined that the aggregate shock criterion is met, else responsive to determining that the aggregate shock criterion is not met, control the discharge circuit to not discharge the stored electrical charge through the patient for at least 27 min from when it is determined that the aggregate shock criterion is not met.
