Sažetak
Objective: To investigate the importance and indications of head-up tilt-testing (HUTT) in patients with unexplained syncope. Methods: We retrospectively analysed 235 patients who underwent HUTT, between February 2012 and September 2014, at Department of Cardiology, University Hospital “Sestre Milosrdnice”. They were divided in three groups according to the HUTT indications as follows: Group A (convulsive syncope, n=30), Group B (suspected vasovagal syncope, n=180) and Group C (paroxysmal vertigo, n=25). The groups were analysed by their baseline parameters (age, gender, referral specialists (cardiologists, neurologists, others)), HUTT results (positive/negative) and specific responses (cardioinhibitory, vasodepressor, or mixed). Results: Groups A and B were referred most frequently to the HUTT by neurologists and cardiologists (p<0.05). It was positive in 34 (14.5%) patients (5 in Group A and 29 in Group B), i.e. 13 (38.2%) patients had cardioinhibitory, 11 (32.4%) mixed and 10 (29.4%) vasodepressor response. In cardioinhibitory subgroup, there were 3 patients (23.1%, 2 males/1 female, mean age 28.5 years) with normal EEG and on antiepileptic drugs. During HUTT, they had typical convulsions with cardioinhibition and bradycardia (heart rate (HR) 30.0±5.0 beats/min) followed by asystole (13.7±11.0 seconds). These three subjects got a permanent DDDR pacemaker (atrial/ventricular stimulation, HR control) and anticonvulsive therapy was slowly withdrawn. They had no syncope recurrences during 24 months of follow-up. Conclusion: HUTT has an important role in evaluation of the patients with unexplained syncope. It is indicated in differential diagnosis of vasovagal syncope, especially in patients with syncope accompanied with convulsive elements. Finally, pacemaker implantation is effective in preventing syncope relapses in patients with cardioinhibitory convulsive snycope.
