1 Dichotomous roles of TBX3 in the establishment of atrioventricular conduction pathways in the human heart  Hoang H. Nguyen, MD, Dorothy K. Grange, MD, Mark C. Johnson, MD, George F. Van Hare, MD, FHRS, Patrick Y. Jay, MD, PhD  HeartRhythm Case Reports  Volume 5, Issue 2, Pages (February 2019) DOI: /j.hrcr Copyright © 2018 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Ventricular preexcitation and a right bundle branch block were found in a 14-year-old girl who carries a de novo loss-of-function mutation of TBX3. The electrocardiogram (ECG) shown was her first. B: Preexcitation is no longer present after transcatheter ablation of a left-sided accessory pathway. The right bundle branch block remains. This ECG pattern has remained the same after 3 years of follow-up. HeartRhythm Case Reports 2019 5, DOI: ( /j.hrcr ) Copyright © 2018 Heart Rhythm Society Terms and Conditions
