My Life in HRV Biofeedback Research [PDF]
Applied Psychophysiology and Biofeedback, 2022 This paper reviews the published work of me along with my students and close colleagues on the topic of heart rate variability biofeedback (HRVB). It includes early research by Vaschillo documenting resonance characteristics of the baroreflex system that causes large oscillations in heart rate when breathing at resonance frequency, research on heart ...

Spectral estimation of HRV in signals with gaps [PDF]
Biomedical Signal Processing and Control, 2019 Abstract Heart rate variability is commonly quantified following spectral estimation. However, it is often difficult to obtain continuous recordings of beat-to-beat intervals without interruptions due to artefacts, noise or sporadic arrhythmias. Such data loss may be seen as gaps in the recordings, and often results in such signals being discarded ...
