COSTA, Roberto  and  LEAO, Maria Inês de Paula. Brazilian permanent cardiac pacemaker implantation experience: results obtained from the Brazilian Pacemaker Register's data. Rev Bras Cir Cardiovasc [online]. 1995, vol.10, n.2, pp.84-89. ISSN 0102-7638.

BACKGROUND: Brazilian Pacemaker Registry (RBM) is a nationwide database to collect informations about all permanent pacemaker procedures performed in Brazil. It is a task force composed by Medical Society, Health Ministeryand Pacemaker Companies. OBJECTIVE: To report the data obtained from June to December, 1994. METHODS: From June 1 st to December 31,1994,4696 surgical procedures for permanent cardiac pacing were informed. These procedures were 3403 (72,5%) initial implantations, 1053 (22.4%) re-operations and in 240 cases this information was non-available. RESULTS: From 3403 initial implantations informed, 52.8% were males and 73.7% Caucasians. Preoperative dizziness or syncopes were refered in 76.4% and congestive heart failure in 85.0% of the patients. EKG evaluation showed 3rd degree atrioventricular (AV) block in 57.7%, sick sinus syndrome in 13.9%, 2nd degree AV block in 13.8%, and high degree AV block and flutter or atrial fibrillation in 6.6% of patients. Chaga's disease was the prédominât ethiology (30.4%). Ventricular pacemakers were implanted in 83.6% of cases, atrioventricular in 16.1 % and atrial pacing in 0.3%. In the 1053 cases of re-operation, the interval between the initial implantation and the present procedure ranged from 1 month to 24 years (M=7.1 years). Pulse generator replacements were refered in 917 patients (87.0% of re-operation procedures), 65.7% of them at the end of life. Atrial lead replacement were performed in 21, and ventricular lead replacement in 203 patients.
