Fragmented QRS Complex: A Novel Marker of Cardiovascular Disease [PDF]

Clinical Cardiology, 2010
AbstractQRS complex fragmentation, defined as changes in QRS morphology with different RSR′ patterns: additional R waves, notched S wave, or > 1R′ wave, has recently been linked with various cardiac conditions and even been postulated to be predictive of outcomes in certain pathologies.

Fragmented QRS – A simple bedside non invasive predictor of early mortality and morbidity in STEMI [PDF]

Al Ameen Journal of Medical Sciences, 2016
Background and objectives: Fragmented QRS encompasses different RSR’ patterns showing various morphologies of the QRS complexes with or without the Q wave on a resting 12-lead electrocardiogram.

Correlation of fragmented QRS complexes with the severity of CAD (using Syntax score) in patients with non-ST elevation acute coronary syndromes

The Egyptian Heart Journal, 2016
Background: Fragmented QRS (f-QRS) complexes are novel electrocardiographic signals, which reflect myocardial conduction delays in patients with coronary artery disease (CAD).

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

Journal 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'), notching of the single R wave, notching of the S wave in at least two contiguous leads on the 12 ...

The Relationship Between fragmented QRS Complexes (fQRS) and the Severity of Coronary Artery Lesion in Coronary Artery Disease: A Cross-sectional Study

Acta Medica Indonesiana, 2022
Background: The severity of coronary artery lesion is commonly used as a predictor of mortality, major adverse cardiovascular event, and revascularization in coronary artery disease (CAD).

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.

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

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 ...
