1. A component of a wearable cardiac defibrillation (WCD) system, the WCD system including a support structure configured to be worn by a patient, sensing electrodes configured to capture at least two ElectroCardioGram (ECG) signals of the patient, and defibrillation electrodes configured to transport electrical charge, the component comprising:

  • an energy storage module configured to store an electrical charge;

    a discharge circuit coupled to the energy storage module; and

    a processor configured to;

    make a certain aggregate shock/no shock determination from at least two of the ECG signals, in which respective individual shock/no shock recommendations are made from each of the at least two of the ECG signals, the respective individual shock/no shock recommendations having a form of respective certainty values, and the certain aggregate shock/no shock determination is made from a statistic of the respective certainty values, andcause, if the certain aggregate shock/no shock determination is to shock, the discharge circuit to discharge the stored electrical charge through the defibrillation electrodes so as to defibrillate the patient.
