Area asymmetry of heart rate variability signal

Area asymmetry of heart rate variability signal

BACKGROUND Heart rate fluctuates beat-by-beat asymmetrically which is known as heart rate asymmetry (HRA). It is challenging to assess HRA robustly based on short-term heartbeat interval series. METHOD An area index (AI) was developed that combines the distance and phase angle information of points in the Poincaré plot. To test its performance, the AI was used to classify subjects with: (i) a...

Signal Processing Methods for Heart Rate Variability

تغییرپذیری ضربان قلب Heart rate variability))

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

Heart rate variability and heart rate asymmetry analysis: does the inspiration/expiration ratio matter?

TO THE EDITOR: In the Journal of Applied Physiology, Wang et al. (2) published their studies on the effects of paced breathing at different inspiration/expiration (I/E) ratios on spontaneous baroreflex sensitivity (BRS), heart rate variability (HRV), and heart rate asymmetry (HRA). The authors concluded that the I/E ratio need not to be set in BRS or spectral HRV analysis. In our recent work (1...
