Abstract

Heart rate variability were registered in 377 women using two diagnostic systems («Valenta» and «Neuron-Spectrum-3»). It is shown that in the I trimester of pregnancy HRV (which indicates an increase in effectiveness of adrenergic effects on heart rate) is reduced. HRV reaches the minimum level in the II trimester and remains at this level in the III trimester. For 10–5 days before the birth HRV partially recoveres, remaining at that level in the I stage of labor, and decreases again (according to O. Polyanskaya, 2009) in II and III stage of labor. HRV is gradually restored (but not entirely) in the first 5 days after delivery. HRV changes due to the presence of endogenous modulators of adrenergic and choline reactivity.
