Wide QRS complex tachycardia in patients with Chagas’ disease: Sustained ventricular tachycardia until proven otherwise

Algorithms used for the differential diagnosis of wide QRS complex tachycardia are extremely important in clinical practice, but they have limitations and should be applied with caution. We describe a case of a patient with positive serology for Chagas disease and normal echocardiogram who presented...

Description
Summary:	Algorithms used for the differential diagnosis of wide QRS complex tachycardia are extremely important in clinical practice, but they have limitations and should be applied with caution. We describe a case of a patient with positive serology for Chagas disease and normal echocardiogram who presented an episode of wide QRS complex tachycardia. It was initially diagnosed as sustained ventricular tachycardia using the Brugada and Vereckei algorithms and it was sent to the reference service for the implant of a cardioverter defibrillator. However, the clinical history, electrocardiogram in sinus rhythm and the electrophysiological study were fundamental to the correct diagnosis and treatment of a posterolateral atrioventricular accessory pathway.
