1 Functional permanent 2:1 atrioventricular block treated with cardioneuroablation: Case report 
Tolga Aksu, MD, Sukriye Ebru Golcuk, MD, Tümer Erdem Guler, MD, Kıvanç Yalin, MD, Ismail Erden, MD  HeartRhythm Case Reports  Volume 1, Issue 2, Pages (March 2015) DOI: /j.hrcr Copyright © 2015 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Baseline ECG showing 2:1 AV block. B: After atropine bolus, 2:1 AV block immediately turns to Mobitz type 1 AV block. C: Normal AV conduction is achieved at the late stage of atropine sulfate infusion. HeartRhythm Case Reports 2015 1, 58-61DOI: ( /j.hrcr ) Copyright © 2015 Heart Rhythm Society Terms and Conditions

3 Figure 2 A: Fibrillar atrial myocardium potentials (heterogeneous and coarse segmented spectrum) (arrow) on intracardiac electrograms. B: Compact atrial myocardium potentials (homogeneous spectrum) on intracardiac electrograms. Bipolar endocardial electrograms are displayed at filter settings of 300–500 Hz at a sweep speed of 400 mm/s. ABLd = distal electrode of ablation catheter ; ABLp = proximal electrode of ablation catheter; CSd = distal electrode of coronary sinus catheter; CSp = proximal electrode of coronary sinus catheter.

4 Figure 3 Anatomic illustration of ganglia A and C in lateral (A) and anteroposterior (B) views. CS = coronary sinus; IVC = inferior vena cava; LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; RAA = right atrial appendage; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein; SVC = superior vena cava.

5 Figure 4 Electrogram-guided ablation. Left lateral (left) and anteroposterior (right) views of a 3-dimensional construction of the right atrium (blue) and left atrium (gray). Focal applications of radiofrequency energy were delivered at sites that displayed fibrillar electrograms. Brown tags indicate ablation sites. IVC = inferior vena cava; LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; MA = mitral annulus; RAA = right atrial appendage; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein; SVC = superior vena cava; TA = tricuspid annulus.
