Association of Anti-Ro Antibodies with ECG Abnormalities in Systemic Lupus Erythematosus: A Cross-Sectional Study in a University Hospital

Novelty in Biomedicine
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with various cardiovascular manifestations. Anti-Ro antibodies are commonly found in SLE patients and may contribute to cardiac abnormalities, including electrocardiographic ...

Fragmented QRS on surface electrocardiogram as a predictor of perfusion defect in patients with suspected coronary artery disease undergoing myocardial perfusion imaging

Indian Heart Journal, 2018
Background: Fragmented QRS (FQRS) on surface electrocardiogram (ECG) is associated with the presence of myocardial scar tissue and may have prognostic value after certain ischemic events.

Low level and high frequency fragmentation of the QRS changes during acute myocardial ischemia in patients with and without prior myocardial infarction [PDF]

, 2014
High frequency (HF) QRS fragmentation and very-low amplitude abnormal intra-QRS potential (uAIQP) analyses have been used to track ischemic changes during coronary artery occlusions.

Early Repolarization, Fragmented QRS and Tpeak-Tend Interval as Electrocardiographic Markers in Patients with Idiopathic Ventricular Arrhythmias: a Brief Review

Journal of Cardiac Arrhythmias, 2020
Introduction: Idiopathic ventricular tachycardia and ventricular fibrillation, as causes of sudden cardiac death, are entities with mechanisms poorly studied and understood to date. The electrocardiogram (ECG) is a simple tool, but with great diagnostic

AI-enabled detection of QRS fragmentation from 12-lead electrocardiogram and its clinical relevance for predicting malignant arrhythmia onset

Frontiers in Cardiovascular Medicine
BackgroundElectrocardiographic markers differentiating between death caused by ventricular arrhythmias and non-arrhythmic death could improve the selection of patients for implantable cardioverter-defibrillator (ICD) implantation. QRS fragmentation (fQRS)

Simple ECG-based score and clinical parameters to predict right ventricular dilation in patients with repaired tetralogy of fallot

Open Heart
Background Cardiac magnetic resonance (CMR) is the gold standard for assessing right ventricular (RV) function in repaired tetralogy of Fallot (rTOF), but it is expensive and not always available. ECG is a cost-effective, accessible alternative.

Prevalence and determinants of low QRS voltages and QRS fragmentation in children and adolescents undergoing sports preparticipation screening [PDF]

Aims: Low QRS Voltages (LQRSV) in limb leads and QRS fragmentation (FQRS) are possible electrocardiographic signs of myocardial fibrosis and cardiomyopathy, but they are not listed in current criteria for interpretating athlete's ECG. We investigated the

Single Derivation Fragmented QRS Can Predict Poor Prognosis in Successfully Revascularized Acute STEMI Patients

Arquivos Brasileiros de Cardiologia
Background: QRS fragmentation (fQRS) is classically defined as the presence of slurred QRS morphology in at least two contiguous leads, and its prognostic importance has been shown in ST elevation myocardial infarction (STEMI).
