Permanent cardiac pacing for neurocardiogenic syncope.

Vasovagal syncope is not a benign condition in the elderly population. In patients not responsive to conservative therapy and whose abrupt faints are associated with serious injuries and seriously affected quality of life, pacemaker therapy was suggested. However, the usefulness of cardiac pacing for the prevention of recurrences of vasovagal syncope remains controversial because of the dominant role of the vasodepressor component during the episode. In the Medical Center Alkmaar, the Head-Up Tilt Test (HUTT) has been used since 1996 during the work-up of patients who present with vasovagal syncope. The HUTT showed a dominant cardioinhibitory response in 4.5% of our patients; in elderly patients with vasovagal syncope without prodromal symptoms and refractory on conservative therapy, pacemaker therapy was very effective in preventing syncope during long-term follow-up.
