[Use of beta-blockader visken in children with primary arterial hypertension].

The effect of Visken was analysed in children with primary arterial hypertension, Stage IB, with reference to their general state, dynamics of cardiac contractions, arterial pressure, cardiac output, and vascular peripheral resistance. The treatment was undertaken in 28 children lasting from 6 to 8 weeks. A multiformity of the drug's effect upon the state of the children with early hypertension was noted. The response of different parameters of the circulatory system to Visken is individual. Side effects may develop against the background of even low doses.
