We report 3 cases of irregular, narrow complex tachycardia misdiagnosed and treated for atrial fibrillation. The adenosine response, detection of recurring triple cycle length variation patterns, and pseudo-R-wave in lead V during tachycardia made us suspect typical atrioventricular nodal re-entrant tachycardia. The electrophysiology study confirmed atrioventricular nodal re-entrant tachycardia, and symptoms were resolved by slow pathway modification.

BACKGROUND Second-degree atrioventricular (AV) block is a frequently encountered conduction abnormality on surface electrocardiogram (ECG). However, it does not always imply a block at the AV nodal level. In rare cases, this block can occur below the bundle of His, within the infra-Hisian region of the His-Purkinje system.

Introduction: The slow atrioventricular nodal pathway (SP) typically has a single atrial breakthrough site.
Methods And Results: We report a case of fast-slow type AVNRT with two distinct atrial breakthrough sites during tachycardia. The earliest atrial activation site (EAAS) was at the right inferior septum, followed by the inferolateral wall of the tricuspid annulus.
The pacing maneuvers for supraventricular tachycardia with cycle length alternans are sometimes difficult, especially when diagnostic ventricular pacing does not conduct to the atrium. Even in such a situation, critical diagnostic findings can be obtained by spontaneous premature ventricular contraction.
