In 35 children of either sex, aged 11-15 years with orthostatic disturbances and in 35 children of the same age without these disturbances, the maximal blood flow rate was assessed in the common carotid artery using Doppler technique during 10-minute passive orthostatic test on a tilting table. During passive tilting to upright position, the mean values of the maximal blood flow rate in the children with orthostatic disturbances were lower than those in the healthy children. The measurement of the maximal blood flow rate in the common carotid artery by the Doppler method may be a useful clinical method of detection of functional cardiovascular disturbances connected with body position in children.
