Incessant atrial ectopic tachycardia can cause significant myocardial dysfunction requiring repeated ablation, as shown in a teenager initially misdiagnosed with sinus tachycardia.
Highlights the importance of recognizing atrial ectopic tachycardia as a potential cause of myocardial dysfunction in young patients presenting with presumed sinus tachycardia.
Absolute Event Rate: 0% vs 0%
Atrial ectopic tachycardia (AET) is an uncommon but important etiology of supraventricular tachycardia. When it occurs and is incessant, it can cause significant myocardial dysfunction. We present a case of a teenager with a history of illicit drug use and anxiety who was presumed to have sinus tachycardia who subsequently was diagnosed with AET with myocardial dysfunction requiring repeated ablation.
