1 Atrioventricular nodal reentrant tachycardia: Evidence of an upper common pathway in some patients 
Claudio Hadid, MD, Sergio Gonzalez, MD, Jesús Almendral, MD, PhD  HeartRhythm Case Reports  Volume 4, Issue 6, Pages (June 2018) DOI: /j.hrcr Copyright © 2018 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Fast–slow atrioventricular nodal reentrant tachycardia induced in case 1. B: Wenckebach AV conduction during continuous pacing at the tachycardia cycle length in the same patient. DCS = distal coronary sinus; HBE = His-bundle electrogram; MCS = middle coronary sinus; PCS = proximal coronary sinus; RVA = right ventricular apex.

3 Figure 2 A: Slow–fast atrioventricular nodal reentrant tachycardia induced in case 2. B: Wenckebach AV conduction during continuous pacing slower than the tachycardia cycle length in the same patient. ABL = ablation catheter placed on the triangle of Koch; HRA = high right atrium; RV = right ventricle.

4 Figure 3 A: Double AV response during right atrial pacing in case 3. B: Induced tachycardia showed retrograde HA Wenckebach block, followed by dissociation of the right atrium from the tachycardia. HBE = His-bundle electrogram; HRA = high right atrium. *Sinus p wave. HeartRhythm Case Reports 2018 4, DOI: ( /j.hrcr ) Copyright © 2018 Heart Rhythm Society Terms and Conditions
