Wearable cardioverter defibrillator (WCD) system informing patient that it will not shock responsive to just-self-terminated cardiac arrhythmia

摘要

In some embodiments, a wearable cardioverter defibrillator (“WCD”) system comprises a support structure configured to be worn by a patient, a power source, an energy storage module configured to be coupled to the support structure, to be charged from the power source and to store an electrical charge, 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 a physiological input from a patient physiological signal, a user interface configured to output one or more human-perceptible indications, and a processor. The processor can be configured to detect a cardiac arrhythmia of the patient from the physiological input, determine whether a type of the cardiac arrhythmia is at least one of a first type (“CA1”) and a second type (“CA2”), if the type is CA1, cause a first human-perceptible indication to be output, else if the type is CA2, cause a second human-perceptible indication to be output, the second human-perceptible indication being different from the first human-perceptible indication, and then control the discharge circuit to deliver a shock responsive to the cardiac arrhythmia.
