To Compare Various Filters for Removal of Noise from ECG Wave

Abstract: An ECG or Electrocardiogram is the reflection of the on-going activities of our heart represented graphically. An ECG waveform tries to tell us how the mechanical movements are going on inside the heart and how better they are functioning. ECG is a good tool to analyse the condition of our heart and has a great clinical importance. There exists various types of noise, which here we can say artifacts, affect the quality of an ECG. Here quality refers to the different performance parameters like Signal to Noise Ratio, Mean Square Error etc. This paper deals with the study of various types of noise and applications of various filters and comparing their performance on the basis of these performance metrics. All the results are simulated in Matlab.

Keywords: ECG, Filter, AWGN, SNR, MSE.
