BACKGROUND Although QRS duration >180 ms has prognostic value in adults with tetralogy of Fallot (TOF), its sensitivity to predict mortality is low. Fragmented QRS complexes, a simple measurement on ECG, are related to myocardial fibrosis and dysfunction in patients with TOF. Our objective was to determine whether QRS fragmentation predicts major outcomes in TOF. METHODS This multicentre study included adult patients with TOF from a prospective registry. Notches in the QRS complex in ≥2… CONTINUE READING
