Ebstein Anomaly With QRS Fragmentation on Electrocardiogram [PDF]

Journal 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: Diagnostic and prognostic significance [PDF]

Cardiology Journal, 2012
Fragmentation of QRS (fQRS) complex is an easily evaluated non-invasive electrocardiographic parameter. Fragmentation of narrow QRS is defined as presence of an additional R wave (R') or notching in the nadir of the S wave, or the presence of > 1 R' in 2 contiguous leads, corresponding to a major coronary artery territory on the resting 12-lead ECG ...

QRS fragmentation is superior to QRS duration in predicting mortality in adults with tetralogy of Fallot

Heart, 2016
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.

Assessment of QRS duration and presence of fragmented QRS in patients with Behçet’s disease

Coronary Artery Disease, 2013
QRS prolongation and the presence of QRS fragmentation in 12-lead ECG are associated with increased mortality and sudden cardiac death in the long term. In this study we aimed to assess QRS duration and fragmentation in patients with Behçet's disease (BD).A total of 50 patients (mean age 42.7±12.0 years) previously diagnosed with BD were recruited.

Diffuse Fragmented QRS as an Index of Extensive Myocardial Scar

Indian Pacing and Electrophysiology Journal, 2010
A 70-year-old man with history of previous myocardial infarction was referred for cardiac resynchronization therapy (CRT) implantation. Echocardiography showed global wall motion abnormality and non-viable myocardium with ejection fraction of 15% and ...

A Machine-Learning Approach for Detection and Quantification of QRS Fragmentation [PDF]

IEEE Journal of Biomedical and Health Informatics, 2019
Fragmented QRS (fQRS) is an accessible biomarker and indication of myocardial scarring that can be detected from the electrocardiogram (ECG). Nowadays, fQRS scoring is done on a visual basis, which is time consuming and leads to subjective results. This study proposes an automated method to detect and quantify fQRS in a continuous way using features ...

Assessment of QRS duration and presence of fragmented QRS in patients with celiac disease

International Journal of Medical Sciences
Background: Celiac Disease (CD) is characterized by small intestine involvement. However, cardiac manifestations may also be seen in the clinical course. The significance of the QRS prolongation and the presence of QRS fragmentation (fQRS) has been previously studied in many chronic inflammatory disorders as an independent predictor of cardiac ...

Evaluation of QRS duration and presence of fragmented QRS in patients with inflammatory bowel disease

International Journal of Medical Sciences
Background: Inflammatory Bowel Disease (IBD) is mostly characterized by gastrointestinal tract involvement, however can also be accompanied with cardiac manifestations. QRS prolongation and the presence of QRS fragmentation (fQRS) have been previously evaluated in many chronic inflammatory diseases, as an independent predictor of cardiac events.

153 Fragmented QRS in athletes [PDF]

European Heart Journal Supplements, 2021
Abstract Aims Fragmented QRS (fQRS), defined as the presence of additional peaks within the QRS complex (<120 ms) in at least two contiguous leads, was considered as a pattern of fibrosis. However, fQRS can also be detected during pre-participation cardiovascular screening.
