Cardiac autonomic regulation under hypnosis assessed by heart rate variability: spectral analysis and fractal complexity

Objective This study examined the effects of hypnosis on autonomic cardiac control. We hypothesized a modification of autonomic modulation of the heart rate with an enhanced vagal tone during hypnosis compared to baseline. Methods In 12 healthy subjects (6 men and 6 women, 22.2 +/- 1.0 years of a…
