Overview
ACC/AHA recommends electrophysiology testing in some groups of patients with dextro-transposition of the great arteries

==(ACC/AHA) recommendations for Electrophysiology Testing Issues in Dextro-Transposition of the Great Arteries (DONOT EDIT)==

Class I

1. Clinicians should be mindful of the risk of sudden arrhythmic death among adults after atrial baffle repair of d-TGA. These events usually relate to ventricular tachycardia (VT) but may be caused in some cases by rapidly conducted intra-atrial reentrant tachycardia (IART) or progressive atrioventricular (AV) block. (Level of Evidence: B)

2. Consultation with an electrophysiologist who is experienced with CHD is recommended to assist with treatment decisions. (Level of Evidence: B)

3. Pacemaker implantation is recommended for patients with d-TGA with either symptomatic sinus bradycardia or sick sinus syndrome. (Level of Evidence: B)

Class IIa

1. Routine surveillance with history, electrocardiogram (ECG), assessment of RV function, and periodic Holter monitoring can be beneficial as part of routine follow-up. (Level of Evidence: B) For ACC/AHA Level of evidences and Classes click :ACC AHA Guidelines Classification Scheme
