Overview

RBBB and AV block are common findings on ECG among patients with Chagas disease cardiomyopathy.

Electrocardiogram

• Annual 12-lead ECG is recommended for all (treated and untreated) patients with Chagas disease:
• Abnormal 12-lead ECG warrant further cardiac evaluation:

• Echocardiography
• Ambulatory ECG evaluation
• Electrophysiological studies

Common ECG Findings

• RBBB
• AV blocks
• Tachyarrhythmias
• Bradyarrhythmias
• Sinus node dysfunction
