FIELD: medicine, applicable for treatment of children with functional cardiopathy. SUBSTANCE: interference therapy is conducted from an "AIT" apparatus by the frontooccipital method in the period of adaptation two days in succession, then every other day, one procedure is served at a frequency of pulses within 90-100 Hz, 3 min, with a subsequent transfer to frequencies within 50-100 Hz - 3 min; the second procedure, at frequency of amplitude modulations within 0-10 Hz, 3 min with a subsequent change-over of the frequency knob to 50-100 Hz, 4 min; the third procedure is served at frequencies within 50-100 Hz, 4 min with a transfer to 0-100 Hz, 5 min; the fourth through the tenth procedures are served at a frequency band within 0-100 Hz, 10 min. Sulfurated hydrogen baths are conducted in the days that are free of interference therapy for girls at concentration of hydrogen sulfide within 25 to 50 mg/l, for boys, within 50-100 mg/l for course of 10 physico- and 8 balneoprocedures.
