Denoising and Artifact Rejection For Cardiac Signal in a Sensis System

摘要

A system denoises and rejects artifacts from cardiac signals, by accepting a cardiac signal from a patient, processing the cardiac signal from the patient using a frequency band width controllable choke to separate the cardiac signal into predefined frequencies, filtering each of the predefined frequencies to remove dynamic common noise, joining each of the predefined frequencies into a cardiac signal without the dynamic common noise, and providing feedback control of the filtering of each of the predefined frequencies.
