Heart Rate Variability and 24-hour Minimum Heart Rate
Biological Research For Nursing, 2006Heart rate variability (HRV) indices based on 24-hr electrocardiograph recordings have been used in clinical research studies to assess the aggregate activity of the autonomic nervous system. Although 24-hr HRV is generally considered noninvasive, use in research protocols typically involves considerable data collection and processing expenses and ...

Heart rate and heart rate variability, a pharmacological target
Cardiovascular Drugs and Therapy, 1997Heart rate varies with respiration, blood pressure, emotion, etc., and heart rate variability (HRV) is presently one of the best indices to predict fatal issues in cardiac failure and after myocardial infarction. HRV depends on various reflexes. In addition, parallel studies of HRV and the myocardial adrenergic and muscarinic transduction system in ...

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.

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 ...
