CPC A61N 1/365 (2013.01) [A61B 5/352 (2021.01); A61N 1/3625 (2013.01); A61N 1/3904 (2017.08)] | 18 Claims |
1. An apparatus of a wearable cardioverter defibrillator (WCD) system, comprising:
a support structure wearable by a patient;
a plurality of electrocardiogram (ECG) electrodes capable of being applied to the skin of the patient to obtain an ECG signal;
a processor to receive and analyze the ECG signal of the patient, wherein the processor is configured to monitor four or more channels of the ECG signal; and
a high voltage subsystem coupled with defibrillation electrodes configured to be coupled with patient, wherein the processor is configured to cause the high voltage subsystem to apply a therapeutic shock to the patient through the defibrillation electrodes in response to a shockable event detected by the processor from the ECG signal;
wherein the processor is further configured to:
measure a peak-to-peak amplitude of QRS complexes of the ECG signal; and
detecting asystole in the patient when the peak-to-peak amplitude of one or more QRS complexes is less than an asystole threshold; and
wherein a unique asystole threshold is set for each of the four or more channels.
