    AbstractThe diagnosis of wide complex tachycardia based on surface electrocardiography can be difficult. Misdiagnosis occurs frequently and is commonly associated with increased morbidity and mortality. We describe a case of wide QRS complex tachycardia in which transesophageal electrocardiography and intravenous adenosine were used to obtain a reliable diagnosis. These are safe and readily available tools for elucidating the mechanism of wide complex tachyarrhythmias in hemodynamically stable patients.
