the rhythm of the heart has not only fascinated cardiologists but also inspired poets and musicians. Indeed, the periodic beat of the heart was used to define the speed of music. In music notation, the traditional Italian term “moderato” originally referred to one beat of the measure per ...

A Practical Guide to the Interpretation of Cardiopulmonary Exercise Tests, 2021
This chapter describes the normal response of the speed of the heart to exercise. The maximum heart rate (HR), or pulse rate, is related to the age of the subject. Failure to reach 80% of the predicted maximum HR is considered abnormal and is sometimes called a high heart rate reserve.

Annals of Internal Medicine, 1993
To present an overview of the applicability of heart rate variability measurements in medicine.During a 4-year period all new papers concerning heart rate variability were collected. A selection of the most recent publications in the presented research area was used for this review.The amount of short- and long-term variability in heart rate reflects ...

Survivors of acute myocardial infarction are at increased risk of sudden cardiac death. Recent trials have demonstrated that in selected high risk post-myocardial infarction patients mortality can be significantly reduced by implantation of an autonomic cardioverter defibrillator.

Current Opinion in Cardiology, 1998
Heart rate variability is a recognized tool for the estimation of cardiac autonomic modulations. Recently, several studies have advanced the field of heart rate variability in three areas: 1) in technical modes of electrocardiogram processing and heart rate variability assessment, 2) in physiologic understanding and interpretation, and 3) in clinical ...

We describe the design of an instrument that can acquire and store the average heart rate of a subject over 256 time intervals of predetermined length (1 or 6 min) during normal daily activities. The instrument consists of two units: a portable recorder, worn by the patient, detects and counts heart beats, and stores their average in memory, and a ...
