Objective: To analyze the electrocardiographic changes in patients with Chagas disease who attended the Hospital José Rangel de Villa de Cura Edo. Aragua, between the years 1998 -2008. Clinical records and electrocardiograms in the archives unit were reviewed. The population consisted of 85 patients with Chagas disease who attended the Hospital José Rangel of Villa de Cura between the years 1998 to 2008. Of these, 64% of patients were aged 60-84 years, 55% of patients were male. Branch block disorder was the most frequent (52,9%), with predominance of right bundle branch block (31,7%), Atrial fibrillation was the most common rhythm disorder (55,3%), with predominance of atrial fibrillation with rapid ventricular response. (3,7%) was also observed ventricular extrasystole, sinus bradycardia, ventricular arrhythmia and other ECG abnormalities, particularly ST-segment abnormalities, alterations in the P wave and low voltage. The major cardiovascular diseases were: hypertension (49,4%), heart failure (57,6) cerebrovascular disease (22,4%). Acetylsalicylic acid was the drug most used (60%), and also Isosorbide (55,3%), Digoxin (35.6%), Amiodarone (29,4%), Furosemide (57,3%), Spironolactone (31,8%), Captopril (44,7%), Enalapril (22,4%) and Clonidine (20%). just 4,7% required the use of pacemakers. Methodology: The research was framed as cross sectional a descriptive epidemiological study. Conclusions: We conclude that in these patients the presence of atrial fibrillation was slightly more common than bundle branch block, with a high frequency of hypertension and heart failure, indicating severe heart failure and poor prognosis.
