A diagnostic challenge of dual atrioventricular nodal nonreentrant tachycardia revealed by ambulatory electrocardiographic monitoring: a case report

BackgroundDual atrioventricular nodal nonreentrant tachycardia (DAVNNT) is an uncommon arrhythmia caused by simultaneous antegrade conduction of a single atrial impulse through fast and slow atrioventricular nodal pathways, resulting in double ventricular activation without a reentrant circuit. Beca...
