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: detect first aspects from at least some of the physiological inputs, generate an aggregated first aspect from at least two of the detected first aspects, determine an aggregate analysis score from the aggregated first aspect, determine whether or not the aggregate analysis score meets an aggregate shock criterion, and if it is determined that the aggregate shock criterion is met control the discharge circuit to discharge the stored electrical charge through the patient within 6 min from when it is determined that the aggregate shock criterion is met, else control the discharge circuit to not discharge the stored electrical charge through the patient for at least 19 min from when it is determined that the aggregate shock criterion is not met.
