Principal component analysis (PCA) is one of the most valuable results oriented techniques of applied linear algebra. PCA is used abundantly in all forms of analysis from neuroscience to computer graphics because it is a simple, non-parametric method of extracting relevant information from confusing data sets. Extracting or decoding this information or feature from ECG signal has been found ver...

Classification of electrocardiogram (ECG) signals plays an important role in clinical diagnosis of heart disease. This paper proposes the design of an efficient system for classification of the normal beat (N), ventricular ectopic beat (V), supraventricular ectopic beat (S), fusion beat (F), and unknown beat (Q) using a mixture of features. In this paper, two different feature extraction method...

Electrocardiogram (ECG) is the record of the heart muscle electric impulses. Received and processed ECG signal could be analyzed, and results could be used for detection and diagnostics of cardiovascular diseases (CVD).One of the important cardiovascular diseases is arrhythmia.This paper deals with improved ECG signal features Extraction using Wavelet Transform Techniques which may be employed ...

Although cardiotocography (CTG) is the most commonly used method in perinatal monitoring. there are still some difficulties surrounding its interpretation. In many cases an unequivocal diagnosis is not possible without additional physiological information. The reasons may be either physiological or due to shortcomings of existing instrumentation. A typical example is shown in Figure 1, where th...

The non-invasive analysis of atrial fibrillation (AF) relies on the extraction of atrial activity from surface ECG recordings. The present study compares three different methods for AA extraction from multi-lead ECG recordings: The adaptive singular value QRST cancellation, the spatio-temporal QRST cancellation and Independent Component Analysis (ICA). A criterion for assessing the performance ...

OBJECTIVE To assess the influence of gender, time of the day and gestational age on fetal heart rate (FHR) parameters between appropriate-for-gestational-age (AGA) and small-for-gestational age (SGA) fetuses using a portable fetal ECG monitor employed in the home setting. METHODS We analysed and compared the antenatal FHR data collected in the home setting on 61 healthy pregnant women with si...
