Yabluchansky N.I., Martynenko A.V.

Heart rate variability: for real doctors. Translation from the Russian version of the book, published at Kharkiv, 2010, 131 p.
The basics and practice of the clinical use of the technology of heart rate variability are outlined for doctors of all specialties and students of medical faculties of universities.

8. Regulation in human health

Body weight

Body weight affects HRV. Lower weight – higher TP and HF, lower weight – on the contrary. Also, a lower weight shows a higher response of HRV to metronomized breathing and high weight shows the same to active orthostasis.
And one more thing – in a subject with severe obesity, shortness of breath may occur, which means the modulation of breathing with increasing TP and HF. In fact, it is one of the variants of a poorly studied stress, with chronically modulated high parasympathetic activity.
A physiological drop in body weight contributes to an increase in the overall power and quality of regulation.

Obesity and HRV. Healthy volunteer, 37 years old. BMI – 42 kg / m2. In the horizontal position: BP – 120/65 mm Hg, HR – 68 beats / min., In the vertical position – BP – 100/60 mm Hg, HR – 72 beats/min. The charts and data in the tables on the left for the horizontal and on the right are the vertical positions. The low TP spectrum of HRV. The increase in the total TP and the ratio of LF/HF in the active tilt test.
