Heart rate variability in patients with recurrent syncope
Journal Title: Archives of Medical Science - Year 2006, Vol 2, Issue 4
Abstract
Introduction: The autonomic nervous system participates in the pathophysiology of vasovagal syncope. The disturbances in the autonomic nervous system can be measured by heart rate variability (HRV). The aim of the study was to assess the usefulness of HRV spectral analysis during HUTT in patients with recurrent syncope. Material and methods: 170 patients with syncope were divided into: positive head-up tilt testing (HUTT) (group I) n=129 and negative HUTT (group II) n=41. The control group comprised 19 healthy volunteers. In all the history was taken, especially with data about syncope and coexisting diseases. Physical examination, 12-lead rest ECG, 24-hour Holter ECG and HRV spectral analysis during HUTT were also performed. Results: Analyzed groups differed in number of syncope, presence of prodromal symptoms (p
