Clinical Trial: Validation of ECG-Based Ventricular Arrhythmia Localization Algorithms in Patients With Repaired Tetralogy of Fallot

U.S., May 27 -- ClinicalTrials.gov registry received information related to the study (NCT07607821) titled 'Validation of ECG-Based Ventricular Arrhythmia Localization Algorithms in Patients With Repaired Tetralogy of Fallot' on May 21.

Brief Summary: Doctors use patterns on heart rhythm tracings (ECGs) to predict where abnormal heart rhythms originate, but these prediction methods were developed in people with normal heart structure. Patients with repaired Tetralogy of Fallot have hearts that developed differently, and we do not know if these prediction methods work accurately for them. In this study, we will test whether three commonly used prediction methods work in Tetralogy of Fallot patients by pacing the heart from known locations d...
