Association of heart rate variability and dispersive electrocardiogram mapping indicators in women during fixed rate breathing test by the period of 10 s are observed. Disturbance of depolarization processes in auricles that show an increase in dispersive group G1 is associated with expressed vagal reserves deficiency. Intensity of control centralization level by heart rhythm and humoral-metabolic influences both in a background and at active breathing can cause intensifying of high-speed microamplitude characteristics of initial front of ventricles depolarization that reflect an increase of dispersive group G9.
