In this paper, we propose a novel method for the detection of myocardial ischemic events from electrocardiogram (ECG) signal, using the Discrete Wavelet Transform (DWT) technique and Support Vector Machines (SVM). The ST-T Segment is obtained based on the detection of R peak location based on the well-known Pan-Tompkins method. Then ratio of energy in the DWT approximation coefficients rather than...
The aim is to characterize the effects of cardiovascular on heart rate variability(HRV) by the nonlinear dynamical parameter complexity measure of the HRV signal. The method is that the electro-cardiogram signals of 20 normal samples and 107 various patient samples are collected. Based on the preprocessing for the raw data, the HRV signals of all samples are extracted from electrocardiogram signals...
This paper presents a comparison of different approaches for performing baseline removal in the electrocardiogram (ECG) signal for use in an ECG based decision support system for diagnosis of coronary heart disease. Our implementations of seven different algorithms for removal of baseline from the ECG signal have been compared which include methods based on use of linear Digital filters, Adaptive...
This paper aims at developing a wearable system able to recognize the most significant cardiac arrhythmias through an efficient algorithm, in terms of low computational cost and memory usage, implementable in a portable, real-rime hardware. In addition, it must respect the specifications of good specificity and sensitivity, in order to permit a positive clinical validation. The hardware is constituted...
Up to now the functioning of the Atrio-Ventricular Junction (AVJ) during Atrial Fibrillation (AF) is still not completely understood. To shed some light on the AVJ behavior during AF episodes, this study analyses the existence of a possible relationship between the occurrence of a heart beat and the power of the atrial activity (AA) preceding this heart beat in an electrocardiogram (ECG) signal. AA...
