In this paper, a new method to remove 60Hz power line interference from ECG (electrocardiogram) in time domain is introduced. The method uses two slope trace waves that are kind of delayed version of original signal with averaged slopes within a certain time interval. After the determination of the two slope trace waves, their arithmetic average is calculated. The result shows filtering effect removing the 60Hz interference. In order to evaluate the effectiveness of the method, several ECGs from MIT-BIH arrhythmia database were chosen and 60Hz sinusoidal waves with different amplitudes were added to them. The simulated ECG was then applied to the algorithm and the result showed its potential applicability to practical signal processing situation requiring effective 60Hz interference removals with minimal waveform distortion.
