The Electrocardiogram signals are a very valuable source of data for physicians in diagnosing heart abnormalities. In this paper, we present an efficient technique for compression of electrocardiogram (ECG) signals. A new thresholding method based on the three level of quantization is proposed for encoding samples using an Embedded Zero-tree Wavelet (EZW) and Huffman algorithms. The modified en...

Capacitive sensing of the electrocardiogram allows inconspicuous monitoring of the most well-known electrophysiological signal. Wheelchair users with cardiac maladies would benefit from ECG unobtrusive monitoring. However, motion and daily life activities impose strong artifacts to the signal acquired. This study aims at the extended capacitive electrocardiogram acquisition with and without mov...

This paper present an electrocardiogram (ECG) beat classification method based on waveform similarity and RR interval. The purpose of the method is to classify six types of heart beats (normal beat, atrial premature beat, paced beat, premature ventricular beat, left bundle branch block beat and right bundle branch block beat). The electrocardiogram signal is first denoised using wavelet transfo...

This chapter describes the application of an intelligent machine learning technique (Support Vector Machines, SVM) to diagnose the patients with sleep apnoea syndrome using Electrocardiogram (ECG) signal. Sleep apnoea syndrome is a medical condition caused by sleep apnoea which is defined as the cessation of breathing for short periods during sleep. First, the importance of early diagnosis and ...

Fetal heart monitoring yields vital information about the fetus health and can support medical decision making in critical situations. A compound signal is obtained non-invasively by placing electrodes on the abdomen area of the mother which contains maternal and fetal ECG signals contaminated by various other signals from body and externally induced noises. The Polynomial Networks technique ha...

The electrocardiogram (ECG or EKG) is a graphic recording of the time-variant voltages produced by the myocardium during the cardiac cycle. The P, QRS, and T waves reflect the rhythmic electrical depolarization and re-polarization of the myocardium associated with the contractions of the atria and ventricles. The electrocardiogram is generally used clinically in diagnosing diseases of the heart...
