AUROCs and AUPRCs were slightly lower than the adult counterpart model [7] in the setting of subtle ASD2-related ECG changes in younger patients (in a recent small single-center study, only adult patients with ASD2 were found to have more striking ECG changes such as complete RBBB, atrial fibrillation, or atrial flutter [1]). This evidence concerns the gene GATA4 and atrial flutter.
