Case study: Monitoring the effectiveness of aromatherapeutic breathing with heart rate variability biofeedback

Heart and Mind, 2021
Heart rate variability (HRV) can be used as an objective measure of mental health and workplace stress. Workplace stress is associated with poor performance and organizations desire optimal performance from employees.

Heart rate and heart rate variability in infants during olfactory stimulation

Annals of Human Biology, 2019
Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, ‘innate’ autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear.

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Determinants of short-period heart rate variability in the general population [PDF]

, 2001
Decreased heart rate variability (HRV) is associated with a worse prognosis in a variety of diseases and disorders. We evaluated the determinants of short-period HRV in a random sample of 149 middle-aged men and 137 women from the general population ...

Heart Rate Variability: New Perspectives on Physiological Mechanisms, Assessment of Self-regulatory Capacity, and Health risk

Global Advances in Health and Medicine, 2015
Heart rate variability, the change in the time intervals between adjacent heartbeats, is an emergent property of interdependent regulatory systems that operates on different time scales to adapt to environmental and psychological challenges. This article
