Wearable cardioverter defibrillator components making aggregate shock/no shock determination from two or more ECG signals
First Claim
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.

Abstract
Components of wearable cardiac defibrillator (WCD) systems, software, and methods are provided. A WCD system includes a support structure that a patient can wear and electrodes that can capture at least two of the patient'"'"'s ECG signals. A component includes an energy storage module that can store an electrical charge, a discharge circuit, and a processor that can make a shock/no shock determination, and cause the discharge circuit to discharge the stored charge, if the determination is to shock. In some embodiments, the processor discards at least one of the ECG signals prior to making the shock/no shock determination. The determination can be made from the remaining one or more ECG signals. In some embodiments, the processor makes an aggregate shock/no shock determination from two or more of the ECG signals.
