1. The cardiovascular reflex changes preceding episodes of vasovagal syncope (VVS) in paediatric age were investigated in 12 subjects and in 20 controls, supine and upright, by spectral analysis of RR interval, respiration, systolic and diastolic blood pressure. 2. The sympatho-vagal control on the heart and blood pressure was assessed by the power of the low- (LF: index of sympathetic activity) and high-frequency oscillations (index of vagal activity to the heart). 3. In VVS group the supine blood pressure was lower than in controls and fell after tilt, while remained unchanged in controls. The blood pressure LF increased in control group during early and prolonged orthostasis, whereas in the VVS group the LF tended to decrease after early orthostasis and were not significantly greater than supine before VVS. 4. In the VVS group the sympathetic control of blood pressure appears reduced or ineffective, and progressively worsens before the VVS episode.
