NCT02573649

Brief Summary

Multicentre, prospective, double blinded, randomized study designed as an intrapatient comparison to evaluate the effects of the Biotronik Closed-loop Stimulation algorithm on prevalence and timing of haemodynamic variations and clinical prodromes induced by head-up tilt test in patients underwent pacemaker implantation for refractory cardioinhibitory vasovagal syncope.
