ABREGO, Hugo Alberto; SUAREZ ARANA, Ricardo  and  SANDOVAL, Álvaro E. Prevalencia de patrones electrocardiográficos tipo Brugada en un centro de monitoreo cardíaco transtelefónico en El Salvador. Rev. costarric. cardiol [online]. 2006, vol.8, n.2, pp.13-17. ISSN 1409-4142.

Aim: Since the diagnostic criteria for the Brugada syndrome were defined, several studies have been made to calculate the electrocardiographic prevalence of this disease. The objective of this study was to define the prevalence of the different Brugada-type patterns in a population with access to transtelephonic electrocardiographic monitoring in El Salvador. Methods: All the electrocardiograms (ECG) received via transtelephonic monitoring at our center between 1/1/2002 and 1/12/2004 were independently analyzed by 2 cardiologists. Results: Alter the exclusion of patients with structural cardiovascular disease, some pattern of Brugada-type ECG was found in 1 patients (0,7%) out of 1166 ECGs from the same number of patients. Average age was 36.4 ± 15.4 years; 64.66 of the patients were male and 35.4% were female. In 5 patients Type 1 pattern was identified (6,17%), none of them had symptoms but an automatic cardioverter defibrillator was implanted in 1 of them because of inducible malignant ventricular arrhytmia. Type 2 was the most frequently found (59 cases, 72,83 and only 17 patients (20,98%) were found to have a Type 3 pattern, all of them were free of symptoms. Conclusion The Brugada-like ECG is not infrequent in this population from El Salvador. There is a Brugada-type pattern for every 144 patients and one case of Type 1 pattern for every 2334 patients of general consultation.
