Gender: male (M), female (F). Clinical Status: cardiac (C), indeterminate (I), mixed (Mi) form of the disease. Treatment outcome after 3 years: non-responder (NR) or responder (R). PCR for T. cruzi presence were performed at 60 days, 6 months, 12 months and 3 years after the beginning of treatment. ECG: Electrocardiogram.
