RESUMO
Objective To investigate the effective therapic methods of the perioperative vasovagal reflex(RV)in patients with atrial arrhythmias(AAs)underwent by catheter ablation .Methods The clinical data in the patients with atrial arrhythmias(AAs) complicated by vasovagal reflex(RV)were retrospectively analyzed during the perioperative procedure of catheter ablation guided by three dimensional mapping system CARTO ;the clinical data were compared between patients with RV and without RV .Results A total of 535 patients with AAs underwent catheter ablation guided by three dimensional mapping system were collected from Janu‐ary 2010 to December 2012 ,and 35 cases of intraoperative RV were found .Compared by patients without RV ,the patients with RV had more elderly cases and the cases of hypertension ,coronary heart disease and diabetes .The RV occurrence was also associated with the fasting ,painful stimuli ,operation time and skill .Conclusion The perioperative RV often is occurred in the cases of high risk and have the precipitating factors ,and the good prognosis could be obtained by the detect and treatment as early as possible .
