Unusual cause of cardiomyopathy in a young woman
Key result
Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) is a rare arrhythmia that can cause tachycardiomyopathy and is poorly responsive to medical therapy, requiring slow pathway ablation.

Population
A young woman presenting with cardiomyopathy caused by dual atrioventricular nodal nonreentrant tachycardia (DAVNNT).
Highlights DAVNNT as a rare but potentially underdiagnosed cause of tachycardiomyopathy that responds poorly to medication and requires slow pathway ablation.

Bares et al. (2021) conducted a case report in Cardiomyopathy caused by dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) (n=1). Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) was evaluated. Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) is a rare arrhythmia that can cause tachycardiomyopathy and is poorly responsive to medical therapy, requiring slow pathway ablation.
