Background: End-stage renal disease patients undergoing hemodialysis (ESRD-HD) therapy are highly susceptible to malignant ventricular arrhythmias caused by undetected potassium concentration ([K+]) variations (Δ[K+]) out of normal ranges. Therefore

Objective The aim of this study is to compare the performance of two electrocardiogram (ECG) lead-space reduction (LSR) techniques in generating a transformed ECG lead from which T-wave morphology markers can be reliably derived to non-invasively mon

Long-lasting periodic sensory stimulation is increasingly used in neuroscience to study, using electroencephalography (EEG), the cortical processes underlying perception in different modalities. This kind of stimulation can elicit synchronized period

Peculiarities of multivariate analysis based methods for detection and evaluation of ECG T-wave alternans

Autor: Krakauskaite, S., Šimoliūnienė, Renata, Petrolis, Robertas, Kriščiukaitis, Algimantas, Kauno technologijos universitetas

Publikováno v: Elektronika ir elektrotechnika, Kaunas : Technologija, 2013, Vol. 19, no. 9, p. 85-88

Two multivariate analysis methods based on Principal Component Analysis and Periodic Component Analysis designed for detection and evaluation of ECG T-wave alternans were tested on synthetic and clinical recordings in the aim to reveal their diagnost
