Autonomic Function

Forty-four CFS patients and 52 healthy adolescents aged 12 years to 18 years were recruited from a pediatric feb-actaoutpatient clinic in Norway. Twenty-four-hour ambulatory blood pressure and heart rate were recorded using a portable device. During night-time sleep, heart rate and mean blood pressure were significantly higher in CFS patients as compared with controls. During daytime, heart rate was significantly higher among CFS patients, whereas blood pressures were equal between the two groups. The findings supportedĀ other evidence of sympathetic predominance of cardiovascular control in adolescent CFS patients and suggested a possible target for therapeutic intervention.
