Low-distortion ECG denoising
First Claim
1. A wireless sensor device for low-distortion denoising of an ECG signal, the wireless sensor device comprising:
- a sensor to detect the ECG signal;
a processor coupled to the sensor, wherein the processor includes a beat selection logic unit; and
a memory device coupled to the processor, wherein the memory device includes an application that, when executed by the processor, causes the processor to;
determine a plurality of beats of the ECG signal for denoising using the beat selection logic unit;
stretch in time the plurality of beats by resampling the plurality of beats of the ECG signal to create a predetermined length for each beat of the plurality of beats;
align the stretched beats of the plurality of beats by aligning peaks of neighboring beats of the plurality of beats; and
denoise the plurality of beats using at least one ensemble averaging filter across the aligned beats of the plurality of beats.

Abstract
A method and system for low-distortion denoising of an ECG signal are disclosed. The method comprises determining at least one beat of the ECG signal for denoising using a beat selection logic and denoising the at least one beat using at least one ensemble averaging filter. The system includes a sensor to detect the ECG signal, a processor coupled to the sensor, wherein the processor includes a beat selection logic unit, and a memory device coupled to the processor, wherein the memory device includes an application that, when executed by the processor, causes the processor to determine at least one beat of the ECG signal for denoising using a beat selection logic and to denoise the at least one beat using at least one ensemble averaging filter.
