ABSTRACT Background: Studies analyzing atrial activation on electrocardiograms (ECGs) have usually highlighted P-wave duration, P-wave dispersion, PR interval, P/PRi ratio, and atrial activation time (AAT). Although these indices can be predictors of atrial fibrillation (AF) in different clinical contexts, no study has analyzed them in the context of Chagas disease (CD). Objectives: To evaluate the following electrocardiographic indices as predictors of AF in CD: P-wave duration, AAT, P-wave dispersion, PR Interval, and P/PRi ratio. Methods: This retrospective study examined ECGs […]
