La variabilité cardiaque

Heart-rate variability (HRV) appears as an excellent indicator to evaluate the activity of the autonomic nervous system, both at the peripheral and central levels. It is also an indicator of the dynamic balance between the sympathetic and the parasympathetic nervous system. This article provides theoretical and empirical support for the emergence of HRV as an important marker of emotion-regulatory ability. Potential clinical applications of HRV also exist, as increasing an individual's capacity for inhibitory-emotion regulation through HRV biofeedback may have therapeutic implications for mood and anxiety disorders and other behavioural disorders. Relaxation and meditation techniques do impact heart-rate variability and can be used, but the most efficient techniques are approaches that combine breathing control, relaxation and meditation exercises and biofeedback-assisted heart-rate variability.
