title: [Short-term effects of stimulation in the right ventricular outflow tract].
abstract: BACKGROUND
  Stimulation in the right ventricular outflow tract (RVOT) showed better clinical and hemodynamic results at short, medium and long term than apical pacing.
  
  
  METHODS
  We enrolled 30 patients undergoing pacemaker implantation with positioning of electrocatheters in the high or low RVOT. All patients underwent clinical, echocardiographic and electrocardiographic evaluation after implantation and at 6-month follow-up.
  
  
  RESULTS
  After 6 months of pacing, no significant changes in echocardiographic parameters were observed, whereas differences were found between the duration of spontaneous QRS and the duration of QRS stimulated at the time of implantation. Electrocatheter implantation in the high RVOT showed a particular benefit.
  
  
  CONCLUSIONS
  Chronic stimulation in RVOT, preferably in the high tract, can be considered a viable alternative to apical pacing in patients with likely high rates of stimulation, especially of young age.
