Spectral Analysis of ECG Signal for Detection of Power Line Interference
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 11
Abstract
ECG signal are usually contaminated by noise which can be within the frequency band of interest. This noise arises due to interference between ECG equipment and electromagnetic field of power lines. This contamination can lead to imprecise measurements of the ECG wave durations and amplitudes. Therefore, the accuracy of the ECG analysis can be significantly reduced. In this paper we have examined the possibility to use Welch method to perform spectral analysis of ECG signal for correct diagnosis.
