Figure (A) Resting electrocardiogram (ECG) showing a bifascicular block with a left anterior hemiblock and a complete right bundle branch block. (B) Cardiac magnetic resonance imaging (MRI) scan, short axis, late gadolinium enhancement, no signs of fibrosis. (C) ECG during spiroergometry with a 2:1 atrioventricular block at a workload of 40 watts. (D) ECG during spiroergometry with high-degree atrioventricular block with a 3:1 conduction, and an appropriate sinus rate of 150 beats per minute. All ECGs shown were written at a speed of 25 mm/s and at 10.0 mm/mV. The American Journal of Medicine 2015 128, e31-e33DOI: (10.1016/j.amjmed.2015.07.026) Copyright © 2015 Elsevier Inc.
