Exponential distribution of long heart beat intervals during atrial fibrillation and their relevance for white noise behaviour in power spectrum
Thomas Hennig, Philipp Maass, Junichiro Hayano +1
The statistical properties of heart beat intervals of 130 long-term surface electrocardiogram recordings during atrial fibrillation (AF) are investigated. We find that the distribu…

1/f Scaling in Heart Rate Requires Antagonistic Autonomic Control
Zbigniew R. Struzik, Junichiro Hayano, Seiichiro Sakata +2
We present the first systematic evidence for the origins of 1/f-type temporal scaling in human heart rate. The heart rate is regulated by the activity of two branches of the autono…

Critical Scale-invariance in Healthy Human Heart Rate
Ken Kiyono, Zbigniew R. Struzik, Naoko Aoyagi +3
We demonstrate the robust scale-invariance in the probability density function (PDF) of detrended healthy human heart rate increments, which is preserved not only in a quiescent co…
