Performance Analysis of ECG Signal Using Various Window Filtering Techniques

Electronics and Communication

ECG signal is of nature of time varying that is most common source used for the diagnosis purpose and observation and analysis of heart diseases present in the patient. ECG is recorded by placing electrodes at specified positions of human body. During recording, ECG is sullied with noises and artifacts which always degrade its quality, and creates accurate and automatic interpretation more difficult. Mostly noticed artifacts or noises are Power line interference, baseline wanders and muscle tremors. So for accurate explanation of characteristics points of ECG, a good quality of ECG is necessary. This paper is presenting a review on various methods for comparing the performance of the digital filter for ECG signal using PSNR, delineation of characteristics points and classification of diseases along with their respective advantages and disadvantages.
