BACKGROUND: @entity1526 ( @entity1526 ) used to be a disease restricted to Latin America, but has become a worldwide problem due to @entity281 individuals to developed countries. Electrocardiography has been considered an essential exam to evaluate @entity1526 @entity1 . OBJECTIVE: This study sought to identify prevalent @entity854 in a large sample of @entity1526 @entity1 evaluated in the primary care setting. METHODS: This retrospective observational study assessed all consecutive digital 12-lead electrocardiograms (ECG) performed by the Telehealth Network of Minas Gerais, Brazil, from January 1 to December 31, 2011. In that time, the service attended primary care @entity1 in 660 cities in the Minas Gerais province. @entity1526 was self-reported, and the individuals who did not report having @entity1526 were considered noninfected. The prevalence of @entity854 was assessed. RESULTS: Self-reported @entity1526 @entity1 comprised 7,590 (2.9%) of 264,324 @entity1 who underwent ECG during the study period. The mean age for @entity1526 @entity1 was 57.0    13.7 years, and 64.1% of @entity1 were @entity1 . The most common comorbidities were @entity101 (61.3%), @entity6 (9.1%), and @entity2299 (6.9%), and 10.7% were smokers. The most frequent @entity854 were nonspecific repolarization abnormalities (34.6%), @entity714 ( @entity714 ) (22.7%), @entity1347 ( @entity1347 ) (22.5%), @entity1540 (5.4%), and @entity955 (5.4%). Only 31.5% of the @entity1 had no electrocardiographic abnormality versus 61.2% in noninfected individuals (p < 0.001). The prevalence of normal ECG decreased with aging and was significantly lower than for noninfected individuals in all age groups. Pacemaker rhythm (odds ratio [OR]: 13.3, 95% confidence intervals [CI]: 11.5 to 15.4), @entity714 (OR: 10.7, 95% CI: 10.1 to 11.4), especially in association with @entity1347 (OR: 12.1, 95% CI: 11.2 to 13.0), second @entity713 (OR: 4.1, 95% CI: 2.5 to 6.6), and third @entity713 (OR: 13.3, 95% CI: 11.5 to 15.4) were strongly related to @entity1526 . CONCLUSIONS: In this large sample of primary care @entity1 with @entity1526 , there was a high prevalence of @entity854 . Pacemaker rhythm, @entity714 , especially in association with @entity1347 , and second and third @entity713 were strongly related to @entity1526 .
