Özet:

 Objective: The value of head-up tilt test HUTT for differential diagnosis of epilepsy and the autonomic nervous system functions in epileptic children using heart rate variability HRV are studied. Patients and Methods: The study group consisted of 16 children with idiopaticcriptogenic epilepsy and 12 controls. Heart rate, PR interval, corrected QT QTc interval, QT and QTc dispersion were calculated using 12-lead electrocardiogram ECG, HRV analysis was performed using the Holter recordings obtained both during HUTT and throughout the day. Time domain parameters, standard deviation of all RR intervals SDNN, the standard deviation of mean NN intervals in five-minutes recording SDANN, mean standard deviation of NN intervals in five-minutes recordings SDNNi, root mean square of successive differences RMSSD, count divided by the total number of all NN intervals pNN50 and frequency domain parameters low frequency LF, high frequency HF, lowfrequency high-frequency ratio LFHF were calculated in both and compared between the two groups. Results: Head-up tilt test was positive in 4 epileptic children 25, none of controls were positive. The heart rate of the patients were higher than the controls p0.015. LFHF ratio in 24-hour Holter recordings, were significantly lower 1.130.6, 1.830.7 respectively, p0.002; the SDANN during HUTT 28.720.2, 18.2  19.9 respectively, p0.024 were significantly higher in the patients than the controls. Conclusion: Head-up tilt test positivity is frequent in epileptic children, and cannot be used in differential diagnosis. HRV calculated both from 24 hour Holter recordings and Holter recordings under orthostatic stress were impaired in favour of parasympathetic system in epileptic children.
