Key result
Transesophageal electrophysiology study successfully aided in the diagnosis of dual atrioventricular nodal nonreentrant tachycardia, leading to successful radiofrequency ablation.
Case Report (n=1)
This is the first report demonstrating the utility of transesophageal electrophysiology study in the diagnosis of dual atrioventricular nodal nonreentrant tachycardia (DAVNNT).
May support transesophageal electrophysiology study for dual atrioventricular nodal nonreentrant tachycardia diagnosis; single case report leaves applicability open for validation.
"Double fire" is generally characterized by 1:2 atrioventricular conduction of sinus beats traveling down fast and slow pathways that result in double ventricular response. When this phenomenon repeats rapidly, dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) occurs. We report a case of an irregular tachycardia with a comprehensive record that includes an electrocardiogram, a transesophageal electrophysiology study, and an intracardiac electrophysiology study. This is the first report of transesophageal electrophysiology study in the diagnosis of DAVNNT. A diagnosis of DAVNNT was deduced, and the patient was successfully treated with radiofrequency ablation of the slow pathway.

Chen et al. (2021) conducted a case report in Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) (n=1). Transesophageal electrophysiology study was evaluated on Diagnosis of DAVNNT. Transesophageal electrophysiology study successfully aided in the diagnosis of dual atrioventricular nodal nonreentrant tachycardia, leading to successful radiofrequency ablation.
