Following the publication of the Task Force document on heart rate variability (HRV) in 1996,
a number of articles have been published to describe new HRV methodologies and their …

Afferent and efferent cardiac neurotransmission via the cardiac nerves intricately modulates
nearly all physiological functions of the heart (chronotropy, dromotropy, lusitropy, and …

Sudden cardiac death (SCD) remains a daunting problem. It is a major public health issue
for several reasons: from its prevalence (20% of total mortality in the industrialized world) to …

Although analysis of heart rate variability is widely used for the assessment of autonomic
function, its fundamental framework linking low-frequency and high-frequency components …

The autonomic nervous system regulates all aspects of normal cardiac function, and is
recognized to play a critical role in the pathophysiology of many cardiovascular diseases. As …

Heart rate at rest and exercise may predict cardiovascular risk. Heart rate variability is a
measure of variation in time between each heartbeat, representing the balance between the …

The importance of resting heart rate (HR) as a prognostic factor and potential therapeutic
target is not yet generally accepted. Recent large epidemiologic studies have confirmed …

Background The rate of death, including sudden cardiac death, is highest early after a
myocardial infarction. Yet current guidelines do not recommend the use of an implantable …

This paper reviews the methods used for editing of the R–R interval time series and how this
editing can influence the results of heart rate (HR) variability analyses. Measurement of HR …

Purpose of this study was to test utility of heart rate variability (HRV) in daily endurance
exercise prescriptions. Twenty-six healthy, moderately fit males were randomized into …
