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 receive an electrical charge from the power source, and to store the received electrical charge;
a discharge circuit coupled to the energy storage module, the discharge circuit controllable to discharge the stored electrical charge so as to cause a shock to be delivered to the patient while the support structure is worn by the patient;
a discharge circuit coupled to the energy storage module, the discharge circuit controllable to discharge the electrical charge so as to cause a shock to be delivered to the patient;
a measurement circuit configured to render physiological inputs from an ElectroCardioGram (ECG) signal of the patient;
a user interface configured to output one or more human-perceptible indications; and
a processor configured to;
detect a cardiac arrhythmia of the patient from one of the physiological inputs;
then determine, from a subsequent one of the physiological inputs, whether or not the detected cardiac arrhythmia is validated according to a validation criterion; and
if the detected cardiac arrhythmia is not so validated, then cause a closing human-perceptible indication to be output, the closing human-perceptible indication configured to communicate to the patient that it was decided not to shock responsive to the detected cardiac arrhythmia, and to further control the discharge circuit to not deliver a shock for at least 25 min from when it was determined that the detected cardiac arrhythmia is not so validated;
else if the detected cardiac arrhythmia is so validated, control the discharge circuit to instead deliver a shock within 2.5 min from when it was determined that the detected cardiac arrhythmia is so validated.

Abstract
In some embodiments, a wearable cardioverter defibrillator (“WCD”) system may output a closing human-perceptible indication, after detecting a shockable cardiac arrhythmia, and after further determining that it will not shock. This may succeed in informing the patient that the WCD system will not deliver a shock responsive to the cardiac arrhythmia, which may have just self-terminated. The information may give comfort to the patient who may be conscious, and may recognize that his or her ventricular tachycardia has self-terminated. Moreover, the patient will know that he or she will not be unnecessarily shocked while conscious, and will not even need to press a cancel switch.
