My daughter of 6 years. At the big load (dances) the augmentation of a pulse rate is observed, cold sweat acts, becomes blue in angles of labiums. The heart disease is not present, but at inspection 3 chorda is found out in the child. What is it can be? In advance thanks for consultation.

[Tutelman K.M.]

The acceleration of pulse (tachycardia) is physiological reaction to a load. As if to cold sweat and blue in angles of labiums it is vegetative reaction. Probably, that the given loads are excessive for the child. And as to an additional chorda it is small anomaly of development of heart and with her the given changes are not connected.
