Abstract:
66 patients with sick sinus syndrome were enrolled in this study. All patients meeting the indications for dual chamber pacing were randomly divided into two groups: right atrial appendage(RAA) pacing group was made up of 36 patients and low atrial septal(LAS) pacing group was made up of 30 patients. Follow-up was 12 months. The incidence of atrial fibrillation(AF) was lower in LAS group(3. 3% ) compared with the RAA group(19. 4% );P wave dispersion in RAA group was significantly higher than that in the LAS group (P < 0. 01). After 3 months of the operation, left atrial volume index(LAVI) in RAA group was significantly larger than that in the LAS group. In LAS group compared with the RAA group P wave dispersion and LAVI were significantly lower after operation in sick sinus syndrome. LAS pacing was superior to RAA pacing in preventing new atrial fibrillation.
