A non-transitory computer-readable storage medium storing one or more programs which, when executed by at least one processor of a wearable cardiac defibrillation (WCD) system, the WCD system including a support structure configured to be worn by a patient, electrodes configured to capture at least two ElectroCardioGram (ECG) signals of the patient and to transport electrical charge, an energy storage module configured to be coupled to the support structure and to store an electrical charge, and a discharge circuit coupled to the energy storage module, the one or more programs result in:
- making a certain aggregate shock/no shock determination from at least two of the ECG signals;
- and
- causing, if the certain aggregate shock/no shock determination is to shock, the discharge circuit to discharge the stored electrical charge through at least two of the electrodes so as to defibrillate the patient.
