Abstract
An electrocardiogram (ECG) acquisition system comprises a processor configured to process an ECG signal from a patient, a plurality of ECG electrodes configured to be coupled to the patient to obtain the ECG signal from the patient, and an analog-to-digital (A/D) converter configured to acquire the ECG signal from the plurality of ECG electrodes, and to provide the ECG signal to the processor as ECG data representative of the ECG signal. The A/D converter is configured to acquire the ECG signal at a first resolution and the processor is configured to process the ECG data at a second resolution, and the first resolution is higher than the second resolution.
Claims5
A wearable cardioverter defibrillator (WCD), comprising:
- a plurality of therapy electrodes configured to be coupled to a patient;
- an energy storage system coupled with the plurality of therapy electrodes;
- a plurality of ECG electrodes configured to be coupled to the patient to obtain an ECG signal from the patient;
- an analog-to-digital (A/D) converter configured to acquire the ECG signal from the plurality of ECG electrodes at a first resolution, and to provide the ECG signal as ECG data representative of the ECG signal;
- and
- a processor coupled with the energy storage system and configured to process the ECG data at a second resolution;
- wherein the first resolution is higher than the second resolution, and
- wherein the processor is configured to determine whether to apply therapy to the patient based on the processed ECG data, and to apply a therapeutic shock to the patient from the energy storage system via the plurality of therapy electrodes when the processor determines that therapy should be applied to the patient.
