Abstract

Introduction: Uncontrolled arterial hypertension brings direct and long-term sequelae in adult age, such as stroke, ischaemic heart disease with myocardial infarction, left ventricular hypertrophy or cardiac arrhythmia. Aim: To assess heart rate variability (HRV) spectral parameters and left ventricular mass in slim children with arterial hypertension, and to search for correlations between these two parameters. Methods: 35 children aged 14.4±3.1 with idiopathic untreated arterial hypertension were enrolled. The control group included 30 age- and gender-matched healthy children (aged 14.1±2.9 years). In all analysed subjects an analysis of HRV parameters (high frequency (HF) and low frequency (LF) components) during 10-minute waking state and sleeping time was performed and left ventricular mass (LVM) as well as the left ventricular mass index (LVMI, g/m2,7) were assessed based on echocardiographic measurements. Results: There was no difference in LF during the waking state and sleep HF between the two groups, whereas HF values during the waking state were significantly lower (p
