Ebstein Anomaly With QRS Fragmentation on Electrocardiogram [PDF]

open access: yesJournal of Investigative Medicine High Impact Case Reports, 2017
Ebstein anomaly is a rare congenital disorder that involves the tricuspid valve and the right ventricle. It is associated with interatrial communication, which allows for paradoxical embolization causing unilateral blindness.

QRS fragmentation versus QRS prolongation in predicting right ventricular enlargement and dysfunction in children and adults with repaired Tetralogy of Fallot [PDF]

open access: yesInternational Journal of Cardiology Congenital Heart Disease, 2023
Patients with repaired Tetralogy of Fallot (rTOF) have risks of late life-threatening sequelae, including right ventricular (RV) dilation and failure, arrhythmias, and sudden death. QRS prolongation is a well-known ECG predictor of these outcomes but has

QRS Fragmentation as a Possible Electrocardiographic Diagnostic Marker in Patients with Acute Myocarditis: Preliminary Histopathological Validation [PDF]

open access: yesESC Heart Failure, 2020
Aims We aim to assess the reproducibility of QRS fragmentation (fQRS) on a multi‐centre dataset of patients with acute myocarditis (AM), including a histopathological validation in a subgroup with biopsy‐proven disease.

QRS fragmentation is associated with increased risk of ventricular arrhythmias in high‐risk patients; Data from the SMASH 1 Study [PDF]

open access: yesAnnals of Noninvasive Electrocardiology, 2022
Introduction QRS fragmentation (fQRS), defined as the presence of additional spikes within the QRS complex, has been associated with myocardial conduction abnormalities and arrhythmogenicity.

Role of QRS Fragmentation for Risk Stratification in Adults With Tetralogy of Fallot [PDF]

open access: yesJournal of the American Heart Association, 2018
Background Patients with tetralogy of Fallot (TOF) remain at risk for cardiovascular events despite successful repair. Some of the current risk stratification tools require advanced imaging and invasive studies, and hence are difficult to apply to ...

QRS fragmentation: its role in sherlocking the arrhythmogenic heart [PDF]

open access: yesJournal of Community Hospital Internal Medicine Perspectives, 2016
The electrocardiogram (ECG) is a commonly available basic diagnostic modality in in-patient, out-patient, and emergency departments. In patients with coronary artery disease (CAD), the presence of a fragmented QRS (f-QRS), which is an extra R wave (R ...

QRS micro-fragmentation as a mortality predictor [PDF]

open access: yesEuropean Heart Journal, 2022
Abstract Aims Fragmented QRS complex with visible notching on standard 12-lead electrocardiogram (ECG) is understood to represent depolarization abnormalities and to signify risk of cardiac events. Depolarization abnormalities with similar prognostic implications likely exist beyond visual recognition

QRS Fragmentation in Preserved Ejection Fraction Heart Failure: Functional Insights, Pathological Correlates, and Prognosis [PDF]

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Fragmented QRS (fQRS) morphology as a surrogate marker of the possible presence of myocardial scarring has been shown to confer a higher risk in patients with reduced ejection fraction heart failure.
