摘要：Normotensive subjects with a family history of hypertension are considered to be at increased risk of developing hypertension. Autonomic control of heart rate is impaired in hypertensive offsprings. Thus the purpose of study was to assess the autonomic activity and hemodynamic variables in young healthy normotensive subjects with parental history of essential hypertension. Method: Sixty young healthy normotensive subjects, with (n = 30) and without (n = 30) parental history of essential hypertension were examined. Autonomic functions were assessed by using heart rate variability analysis. Results: In the present study, no significant differences were observed in hemodynamic variables (blood pressure, cardiac output, stroke volume, heart rate, systemic vascular resistance, blood flow index, pulse arrival time, pulse termination time) in both groups. The low frequency power in normalized units was significantly higher (P
