dc.description.abstractSpectral analysis of heart rate variability was used to assess changes in activity of autonomic nervous system (ANS) in 84 patients with history of recurrent syncope and 21 normal controls. The analysis was done in different phases of tilt table testing procedure to attempt to relate such changes to specific types of response to a trigger such as decrease of arterial blood pressure when standing up. Frequency domain measurements of the high (HF), low (LF) frequency bands and the ratio LF/HF were derived from ECG recordings and computed by Fast Fourier transform (FFT) for a sequential 5 min intervals of the whole 55 min tilt testing procedure. A statistically significant increase of the LF component and decrease of the HF component of the HRV spectrum were observed during the transition from the supine position to head-up tilt (HUT) in subjects with a history of syncope. However, there were no differences in the ANS activity in comparable testing intervals between subjects who experienced syncope, to those who did not. There were also no differences in the ANS activity in subjects with tilt-induced syncope compared to healthy control subjects. We therefore suggest that HRV is a suitable method for investigating the activity of ANS during the head-up tilt table testing, however with existing methodology is not possible to predict the outcome of the head-up tilt table test in its early stages.it_IT
