The heart rate variability (HRV) signal carries important information about the systems
controlling heat rate and blood pressure, mainly elicited by autonomic nervous system …

Heart rate variability (HRV) is a reliable reflection of the many physiological factors
modulating the normal rhythm of the heart. In fact, they provide a powerful means of …

The electrocardiogram is a representative signal containing information about the condition
of the heart. The shape and size of the P-QRS-T wave, the time intervals between its various …

OVER the past 30 years, heart rate variability (HRV) has become a central topic in
physiological signal analysis, serving as a vital noninvasive indicator of cardiovascular and …

The heart is a key component of the human body, acting as a pump that transfers
oxygenated and deoxygenated blood around the body. Like all other organs, it is …

A time-variant algorithm of autoregressive (AR) identification is introduced and applied to the
heart rate variability (HRV) signal. The power spectrum is calculated from the AR coefficients …

There are numerous methods and approaches available for time-series analysis. This
chapter presents selected methods, which are or at least could be useful when analyzing …

A method is described which allows the determination of the causal relationship existing
between two biological signals (heart rate and arterial blood pressure variability signals) …

The analysis of fluctuations in heart rate or heart rate variability (HRV) has found
applications in, among others, the study of the neural cardiovascular system and ergonomic …

Heart rate monitoring is commonly used to provide an acute indicator of an individual's
cardiovascular status and responsiveness. An increasingly popular technique involves …
