Heart rate and heart rate variability in emergency medicine
The American Journal of Emergency Medicine, 2020Tachycardia may be indicative of mental stress, which in turn can decrease performance, reduce information processing capacity, and hinder memory recall. The objective of this study is to examine heart rate trends present among emergency medicine trainees over a standard emergency room shift to measure the frequency and severity of stress experienced ...

Current Opinion in Cardiology, 2016
Resting heart rate has long been thought to be a risk factor in cardiovascular disease and a prognostic factor in heart failure. β-Blockers were originally used in heart failure for their heart rate control abilities. However, they also have negative inotropic effects contributing to their overall benefit.

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1991
Heart rate oscillates on several different time scales and has long-term variability in the form of 1/f noise. The physiological control of heart rate is briefly reviewed, and several typical patterns of heart rate variability, in health and sickness, are described. Considered briefly are some possible dynamical mechanisms for heart rate variability.

Mental load, heart rate and heart rate variability
Psychologische Forschung, 1970"Several investigators have shown that diminished sinus arrhythmia can be seen as an indication of increased mental load. The present experiment deals with the influence of different levels of mental load, operationalized as the number of binary choices per minute, on the regularity of the heart rate. Also . . .

Heart Rate and Heart-Rate Variability: An Attempt to Clarify
Perceptual and Motor Skills, 19682 experiments were conducted to investigate a possible relationship of heart rate among and within individuals and to investigate the relationship between HR level and two temporal measures of HR variability. In Exp. 1 records for 18 normal male volunteers yielded a linear relationship between the autocorrelation and HR level which was confirmed by ...

Heart rate perception and the voluntary control of heart rate
Biological Psychology, 1980Heart rate perception was assessed in two sets of trials by having subjects set an intermittent visual pulse to match their heart rates. Just prior to matching subjects were required to either hyperventilate, hypoventilate or breathe normally to encourage a range of cardiac levels.
