Background: The Amazon region has always been rated as a low-risk area for Chagas disease (CD). Objective: To report on electrocardiographic changes observed in the acute phase of orally transmitted CD. Methods: ECG tracings were analyzed for 161 patients with clinical, serological and parasitological acute phase CD, all probably infected orally, between January 2009 and April 2010, seen at the Hospital das Clinicas Gaspar Viana in Belem, Para State, Brazil. Results: The results showed basically the same classic electrocardiographic changes described for the acute phase of the disease, suggesting no significant differences between myocarditis caused by oral transmission compared to blood and vector transmission. Conclusion: Electrocardiographic changes in acute phase CD are similar to those found when this disease is contracted through vectors in endemic areas.
