Lately, many clinical and academic researches have shown that it is feasible to determine different sleep phases and obstructive sleep apnea (OSA) occurrence without EEG signals, which is always the essential foundation of polysomnography (PSG). In order to conduct further research of OSA screening, we have developed a novel device acquiring some other physiological signals with different sensors...
Automatic detection of atrial fibrillation (AF) for AF diagnosis, especially for AF monitoring, is necessarily desirable for clinical therapy. In this study, we proposed a novel method for detection of the transition between AF and sinus rhythm based on RR intervals. First, we obtained the delta RR interval distri bution difference curve from the density histogram of delta RR intervals, and then detected...
T-wave alternans (TWA) in electrocardiogram (ECG) is associated with an increasing propensity to ventricular arrhythmic and is regarded as an independent indicator of sudden cardiac death (SCD). Various methods have been proposed to detect and quantify TWA in recent years, however, less attention was paid on the pretreatment stage before the final decision step. A detector with spectral method (SM)...
In this work we present a new approach of dot map to analyze heart rate variability (HRV), using the sequence of RR intervals by first order difference, which is based on the mapping approach of Poincare plots. We analyze the characteristic of the plot to obtain its indexes to express HRV, and to detect kinds of premature beats from its ectopic plots area. As the natural RR interval of heart beats...
