Chagas disease (CD), with associated conduction abnormalities, is a common indication for pacemaker implantation in Latin America. The prevalence of CD in Latin American immigrants with pacemakers residing in the United States has never been studied. This single-center cross-sectional study included pacemaker patients who were aged 18 years or more with a previous residence in Latin America for at least 6 months. Patients with an implantable cardioverter-defibrillator, cardiac resynchronization therapy, or iatrogenic and/or congenital heart block were excluded. Serological testing for was performed at enrollment. A total of 80 patients were enrolled, and CD was diagnosed in six patients (7.5%). Patients with CD were more likely to be from El Salvador ( = 0.001). Other clinical, therapeutic, electrocardiographic, and echocardiographic variables were similar between the CD and non-CD groups. There is a high prevalence of CD among Latin American immigrants with pacemakers in Los Angeles.
