The concept of a “polypill” is receiving growing attention to prevent cardiovascular disease.
Yet similar if not overall higher benefits are achievable with regular exercise, a drug-free …

This article updates the 1994 American Heart Association scientific statement on cardiac
rehabilitation. It provides a review of recommended components for an effective cardiac …

Heart rate variability (HRV) is a noninvasive, practical and reproducible measure of
autonomic nervous system function. A heart rate that is variable and responsive to demands …

Organisms have rhythms, such as the rhythms of the cardiac and respiratory systems,
endocrinological networks, brain circuits, awake–sleep rhythms, and so on. All these …

Background Physical inactivity is a leading cause of preventable death and morbidity in
developed countries. In addition physical activity can potentially be an effective treatment for …

The arterial baroreflex contributes importantly to the short-term regulation of blood pressure
and cardiovascular variability. A number of factors (including reflex, humoral, behavioral …

Background—Despite the rational expectation for a survival benefit produced by exercise
training among post–myocardial infarction (MI) patients, direct evidence remains elusive …

Sudden cardiac death resulting from ventricular tachyarrhythmias remains the leading cause
of death in industrially developed countries, accounting for between 300,000 and 500,000 …

Background—Myocardial ischemia and infarction impair baroreflex sensitivity (BRS), which
when depressed is predictive of future cardiac events after myocardial infarction (MI). The …

Increasing attention is being focused on the role of the autonomic nervous system in health
and disease. The complex interplay between sympathetic and parasympathetic components …
