A meta-analysis of heart rate variability in major depression
Psychological Medicine, 2019Background Major depression (MD) is a risk factor for cardiovascular disease. Reduced heart rate variability (HRV) has been observed in MD. Given the predictive value of HRV for cardiovascular health, reduced HRV might be one physiological factor that ...

Assessment of autonomic function in humans by heart rate spectral analysis.
American Journal of Physiology, 1985Spectral analysis of spontaneous heart rate fluctuations were assessed by use of autonomic blocking agents and changes in posture. Low-frequency fluctuations (below 0.12 Hz) in the supine position are mediated entirely by the parasympathetic nervous ...

Heart rate and blood pressure represent the integrated response to ongoing and dynamic changes in autonomic, cortical, environmental, and other inputs. The relatively “coarse” quantification of heart rate and blood pressure nevertheless is invaluable in ...

Smart Homes that Monitor Breathing and Heart Rate
International Conference on Human Factors in Computing Systems, 2015The evolution of ubiquitous sensing technologies has led to intelligent environments that can monitor and react to our daily activities, such as adapting our heating and cooling systems, responding to our gestures, and monitoring our elderly.
