This study evaluated the effectiveness of different types of wavelets and thresholds to process electrocardiograms. An electrocardiogram, or ECG, shows the electrical activity in the heart and can be used to detect abnormalities. The first process used term-by-term thresholding to denoise ECGs. The second process denoised and compressed ECGs using global thresholding. The effectiveness was determined by using the signal-to-noise ratio (SNR) and the percentage root mean square difference (PRD).
