“…Abdelliche et al [52] have performed thresholding on the fused real parts at scale 3 and scale 4 of CWT for making the QRS complexes of the ECG signals more salient, and then implemented the zero-crossing testing on the imaginary part at scale 4 of CWT for locating the QRS complexes. Aqil et al [53] have suggested detecting the R peaks by means of the maxima finding based on the CWT coefficients at scale 6, which corresponds to the maximum energy of the ECG signals. Yochum et al [54] have located the QRS complexes in the ECG signals based on the threshold that is automatically determined by the histogram representation of the CWT coefficients at scale 38.…”

Physiological and pathological information within electrocardiogram (ECG) is crucial for the diagnosis of heart diseases. Computer-aided diagnosis for the ECG signals has drawn growing research attention up to date. Automatic ECG analysis mainly includes signal denoising, wave detection, and heartbeat classification. These three issues are relevant that the signal denoising can help attenuate the noises and accentuate the typical waves in ECG signals for wave detection, and wave detection can help locate the typical ECG waves and acquire the diagnostically valuable heartbeats based on these waves for the heartbeat classification. The wavelet-based methods play important roles in the three issues, but these methods are scattered and unorganized in the literature. In order to manifest the value of these methods, this paper contributes an overview and taxonomy on them. This paper does the comprehensive summary and systematic categorization on the methods for signal denoising, wave detection, and heartbeat classification according to the deep analysis of their methodological characteristics. By doing so, this paper not only uncovers the inner mechanism that why wavelet-based methods are suitable for ECG analysis but also reveals the designing principles that these methods potentially follow. Finally, this paper has provided an outlook for the developing prospect of ''wavelets for ECG'' in the future.

“…Other methods have been recently used by some authors for Electrocardiogram signal denoising. Some of these methods are -Empirical Mode Decomposition (EMD), Independent Component Analysis (ICA), adaptive filtering [6] [7] [8]. In another study it has been observed that FIR and IIR filters show maximum SNR improvement when used to remove powerline interference.…”

Abstract-The electrocardiogram (ECG) will create the characteristic in the form of the wave's peak pattern. The first peak and the next one in one ECG wave have their own value and names, namely PQRST peaks. The process of feature extraction is very significant to determine the certain pattern. The use of feature extraction will be useful to help to detect certain case, including the determination of PQRST peaks according to the ECG print-out. This study makes a method to determine the ECG peaks (PQRST), the heart rate, and ST-deviation according to the ECG graphic image. The input data is in the form of ECG graphic image which is derived from the ECG 12 lead record. This study employs segmentation method (grayscale and binary), morphology (dilation and erosion), and produce the graphic image which is read as the ECG signal in the pre-processing stage, and use the Pan-Tompkins algorithm for the feature extraction method. The result of the peak determination is validated by cardiologists. The validation shows that the result of up and down deflection computation from the isoelectric of each P, Q, R, S, and T wave has represented the ECG calculation clinically; including the calculation to determine the R-R interval, heart rate, and STdeviation.
