title: Response to treatment during medium-term follow-up in a series of patients with neurocardiogenic syncope.
abstract: BACKGROUND
  Syncope is a common symptom that has different recurrence ratios. We hypothesized that an individualized treatment regimen including pharmacologic and nonpharmacologic measures considering kind of neurocardiogenic syncope (NCS) and basal characteristics of each patient could allow optimized therapy to avoid recurrences.
  
  
  METHODS
  We conducted a prospective study to evaluate performance of diverse accepted treatments for NCS. Each patient received specific treatment including general measures such as an increase in salt and water intake, tilt training, specific pharmacologic treatment according to head-up tilt table test (HUTT) result, and patient basal blood pressure and heart rate measurements.
  
  
  RESULTS
  We followed a group of 127 patients during a main period of 20.8 +/- 9 months (range, 6-38 months). Mean age was 47.8 +/- 19.2 years and 66.9% were females. We had six (4.7%) patients with recurrence of symptoms 4 +/- 0.9 months after diagnostic HUTT. Medications used were atenolol in 20 patients, pindolol in 17, dysopiramide in 50, and fluoxetine in 25. Two patients received fludrocortisone. Tilt training was not indicated initially for patients with recurrences but was indicated later; to date, these patients have not experienced further episodes.
  
  
  CONCLUSIONS
  Increase in water and salt intake, as well as tilt training, showed great value in prevention of syncope recurrences in this specific set of patients. Pharmacologic treatment has an important role, but there is no single medication associated with significant improvement in symptom control.
