Heart rate and heart rate variability in emergency medicine

The American Journal of Emergency Medicine, 2020
Tachycardia 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 ...

Heart rate and heart failure

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.

Heart Rate and Heart-Rate Variability: An Attempt to Clarify

Perceptual and Motor Skills, 1968
2 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

Heart rate perception and the voluntary control of heart rate

Biological Psychology, 1980
Heart 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.

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 . . .
