Fragmented QRS as a Predictor of Appropriate Implantable Cardioverter-defibrillator Therapy

Indian Pacing and Electrophysiology Journal, 2014
Background: Fragmented QRS (fQRS) has been shown to be a marker of local myocardial conduction abnormalities and a predictor of cardiac events in selected populations.

The Predictive Value of Fragmented QRS for Cardiovascular Events in Acute Myocardial Infarction: A Systematic Review and Meta-Analysis

Frontiers in Physiology, 2020
Objective: Fragmented QRS (fQRS) have been reported as a predictor of major adverse cardiac events (MACE) and mortality in several studies on cardiovascular disease. However, most studies have yielded discrepant results.

Correlation between QRS Complex Changes and Cardiac Iron Overload in Beta Thalassemia Major Patients Using T2*MRI

Journal of Mazandaran University of Medical Sciences, 2021
Background and purpose: Cardiac magnetic resonance imaging (MRI) is a costly method to assess cardiac iron overload. The presence of fragmented QRS (fQRS) indicates changes due to iron overload in cardiac tissue. The aim of this study was to evaluate the

Prevalence of electrocardiographic markers associated with myocardial fibrosis in masters athletes: a cohort study

BMJ Open Sport & Exercise Medicine
Objectives Myocardial fibrosis (MF) is associated with an increased predisposition to adverse cardiac events. The accumulation of high-volume and high-intensity exercise over an extended duration potentially increases the risk of MF.

Fragmented QRS complex is an independent predictor of plaque burden in patients at intermediate risk of coronary artery disease

Indian Heart Journal, 2019
Objective: We aimed to evaluate the relationship between fragmented QRS complex and plaque burden in patients presented with typical chest pain and deemed to have intermediate pretest probability of CAD using coronary computed tomography angiography ...

Fragmented QRS complexes are a marker of myocardial fibrosis in hypertensive heart disease

Türk Kardiyoloji Derneği Arşivi, 2016
Objective: Carboxy-terminal propeptide of type 1 procollagen (PICP) is a marker of extracellular collagen synthesis. Fragmented QRS (fQRS) on a 12-lead electrocardiogram (ECG) has been demonstrated as a marker of myocardial fibrosis.

Bundle Branch Blocks and Fragmented QRS Complex in Iranian Patients with Systemic Sclerosis

Journal of Tehran University Heart Center, 2019
Background: Cardiac involvement, as one of the life-threatening manifestations of systemic sclerosis (SSc), is chiefly caused by collagen fiber deposition in the myocardium, which subsequently leads to conduction abnormalities.
