Syncope, Vasovagal, Neurally-Mediated
Conditions
Brief summary
Cardioneuroablation is a novel treatment option for reflex-mediated syncope. It involves thermal destruction of neural tissue in the close proximity of heart using catheter introduced to the heart through vein in the groin. Effectiveness of the procedure is satisfactory, however, in some cases there is a possibility of the re-growth of previously ablated tissue. We aim to investigate whether this process could be traced by measurement of various physiological parameters related to heart rate reactivity. Additionally we intend to reveal whether changes in those parameters over time could influence clinical effeciveness of the procedure.
Interventions
Ablation of parasympathetic ganglia of the heart
