Baroreflex Sensitivity and its Association with Arrhythmic Events in Chagas Disease
Background: Sudden death is the leading cause of death in Chagas disease (CD), even in patients with preserved ejection fraction (EF), suggesting that destabilizing factors of the arrhythmogenic substrate (autonomic modulation) contribute to its occurrence.Objective: To determine baroreflex sensitivity (BRS) in patients with undetermined CD (GI), a
