WCD SYSTEM OPERABLE TO NOT ALARM WHEN DETECTED CARDIAC ARRHYTHMIAS ARE NOT VALIDATED
A wearable cardioverter defibrillator (WCD) comprises a support structure to be worn by a patient, an energy storage module to store an electrical charge, a discharge circuit coupled to the energy storage module, a measurement circuit, a user interface that includes a speaker, and a processor. The processor is configured to monitor a physiological signal of a patient with the measurement circuit to detect cardiac arrythmia when the patient is wearing the support structure, determine whether a validation criterion is met in response to detection of a cardiac arrythmia, provide no alarm with the user interface the validation criterion is being determined, and cause a shock to be delivered to the patient from the energy storage module by the discharge circuit in the event the validation criterion is met

21 . A method to operate a wearable cardioverter defibrillator (WCD), the WCD including a support structure worn by a patient, an energy storage module to store an electrical charge, a discharge circuit coupled to the energy storage module, a measurement circuit, a processor, and a user interface that includes a speaker, the method comprising:
monitoring a physiological signal of a patient with the measurement circuit to detect cardiac arrythmia when the patient is wearing the support structure;
determining with the processor whether a validation criterion is met in response to detection of a cardiac arrythmia;
providing an opening human perceptible indication (HPI) with the user interface during said determining; and
delivering a shock to the patient from the energy storage module by the discharge circuit and providing a warning HPI distinct from the opening HPI prior to delivering the shock in the event the validation criterion is met.
22 . The method of claim 21 , wherein the validation criterion comprises the detected cardiac arrythmia lasting longer than a period of time.
23 . The method of claim 22 , wherein the period of time comprises 25 seconds.
24 . The method of claim 22 , wherein period of time comprises 35 seconds.
25 . The method of claim 21 , wherein the patient physiological signal comprises an electrocardiogram (ECG) signal.
26 . The method of claim 21 , wherein providing the opening HPI comprises the user interface providing a lower intensity level alarm during said determining.
27 . The method of claim 21 , wherein providing the opening HPI comprises the speaker making no sound during said determining.
28 . The method of claim 21 , wherein the warning HPI is provided only when the validation criterion is met.
29 . The method of claim 21 , wherein no warning HPI is provided unless the validation criterion is met.
30 . The method of claim 21 , wherein no warning HPI is provided in the event the detected cardiac arrythmia self-terminates before the validation criterion is met.
31 . A wearable cardioverter defibrillator (WCD), comprising:
a support structure to be worn by a patient;
an energy storage module to store an electrical charge; a discharge circuit coupled to the energy storage module;
a measurement circuit;
a user interface that includes a speaker; and
a processor configured to:
monitor a physiological signal of a patient with the measurement circuit to detect cardiac arrythmia when the patient is wearing the support structure;
determine whether a validation criterion is met in response to detection of a cardiac arrythmia;
provide an opening human perceptible indication (HPI) with the user interface while the validation criterion is being determined; and
cause a shock to be delivered to the patient from the energy storage module by the discharge circuit and provide a warning HPI distinct from the opening HPI prior to delivering the shock in the event the validation criterion is met.
32 . The WCD of claim 31 , wherein no warning HPI is provided in the event the detected cardiac arrythmia self-terminates before the validation criterion is met.
33 . The WCD of claim 31 , wherein the validation criterion comprises the detected cardiac arrythmia lasting longer than a period of time.
34 . The WCD of claim 33 , wherein the period of time comprises 25 seconds.
35 . The WCD of claim 33 , wherein period of time comprises 35 seconds.
36 . The WCD of claim 31 , wherein the patient physiological signal comprises an electrocardiogram (ECG) signal.
37 . The WCD of claim 31 , wherein the user interface is configured to provide the opening HPI at a lower intensity level while it is being determined whether the validation criterion is met.
38 . The WCD of claim 31 , wherein the user interface is configured to make no sound with the speaker while it is being determined whether the validation criterion is met.
39 . The WCD of claim 31 , wherein the warning HPI is provided only when the validation criterion is met.
40 . The WCD of claim 31 , wherein no warning HPI is provided unless the validation criterion is met.
