Patent review on Denoising of ECG signal

Pub. no.: US 2015/0018702 A1

The patent contains information about the apparatus and methods to use this apparatus for denoising the electrocardiograms signal (ECGs) where the percentage of amount of filter applied to the signal can be varied manually by the operator or automatically by the program. For the denoising of the signal filter techniques such as filter to correct baseline wander and Savitzky-Golay denoising technique and threshold smoothing is used.

The denoising method given in the patent can be described as

Firstly providing ECG signal to the computing device and applying the filter to the signal. These filtered signal is displayed on the computing device after which the amount of the filter can be adjusted by the medical professional or automatically by the computing device as per the set mode. Here the amount of filtered is applied in real time as the signal is being displayed.

This method provided in patent can be used for processing of ECG signal which can provide improved readability for medical professional for diagnosing ECG signal.
