Comparison and Validity of Fragmented QRS (fQRS) Against Cardiac Magnetic Resonance (CMR) in Predicting Right Heart Function in Tetralogy of Fallot Patients After Reconstructive Surgery
Abstract:Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Patients with repaired TOF (rTOF) expose to moderate to severe pulmonary regurgitation (PR), right ventricular (RV) dysfunction, and RV failure. Although cardiac magnetic resonance (CMR) provides details of RV function and structure, an electrocardiogram (ECG) is accessible and inexpensive. Objectives: We aimed to assess the correlation between clinical symptoms and ECG parameters with CMR findings. Methods: This cross-… Show more
