ECG monitoring was performed using continuous ECG recording in the 24 hours in patients with iron-deficiency anemia (n=16), vitamin B12-deficiency anemia (n=16). Assessed indicators of heart rate variability, atrial late potentials, ventricular late potentials. In patients with diseases of the blood revealed a significant decline of heart rate variability, recorded decrease parasympathetic influence and increase sympathetic nervous system on the heart as compared to healthy. Late ventricular and atrial potentials significantly more common in patients with diseases of the blood, compared to the control group.
