Background—Fragmented QRS complex (fQRS) on 12-lead ECG, a marker of myocardial scar, is a predictor of arrhythmic events in patients with ischemic and nonischemic cardiomyopathy. We investigated whether the presence of fQRS is associated with the severity of the anomaly and with increased arrhythmic events in adult patients with Ebstein anomaly (EA). Methods and Results—In 51 consecutive adult patients with EA (median age, 37 years; 18 males), the severity index of EA calculated from…

The Difference on Features of Fragmented QRS Complex and Influences on Mortality in Patients with Acute Coronary Syndrome.

Investigation of whether the fragmented QRS (fQRS) complexes can be used to distinguish patients with early non-ST elevation myocardial infarction (NSTEMI) from those with unstable angina (UA) found presence of fQRS complexes within 48 hours of presentation to differentiate NSTEMI patients from UA patients.

Short-term Prognosis of Fragmented QRS Complex in Patients with Non-ST Elevated Acute Myocardial Infarction

The fQRS complexes are commonly present in NSTEMI and the fQ RS complexes are an independent predictor of MACE in N STEMI patients, and the number of narrowed coronary arteries, Killip classification, and total cholesterol are all independent predictors of the f QRS complexes.

Presence of fragmented QRS may be associated with complex ventricular arrhythmias in patients with type-2 diabetes mellitus

The presence of fQRS may be used as a predictor of complex VAs and the risk of sudden death in patients with DM.

Fragmented QRS may be associated with complex ventricular arrhythmias in mitral valve prolapse.

The presence of fQRS may be used in risk stratification of complex VAs in patients with MVP and the presence of bileaflet prolapse or notching/splitting of S wave in two contiguous ECG leads were independent predictors forcomplex VAs.

Examining the Correlation Between the GOSE Index and Atrial Arrhythmia Development with Electrocardiographic P-wave Properties in Patients with Ebstein’s Anomaly

Clinicians may have an idea about the prognosis of cases with Ebstein’s anomaly by evaluating the P-wave changes in ECG and especially the development of supraventricular arrhythmia and the GOSE index can be estimated.

Fragmented QRS on surface electrocardiogram is not a reliable predictor of myocardial scar, angiographic coronary disease or long term adverse outcomes.

This study does not support routine assessment of fQRS on surface EKG as a reliable predictor of SPECT myocardial scar, MACE or all-cause mortality over a long period of follow-up.

Aims Sudden cardiac death (SCD) causes a large portion of all mortality in adult congenital heart disease (ACHD) patients. However, identification of high-risk patients remains challenging.

Variations of QRS Morphology in Patients with Dilated Cardiomyopathy; Clinical and Prognostic Implications

An overview on some clinical, echocardiographic and prognostic implications of various QRS morphologies in patients with IDCM is presented.



QRS duration and QRS fractionation on surface electrocardiogram are markers of right ventricular dysfunction and atrialization in patients with Ebstein anomaly.

A preserved surface ECG identifies a subset of patients with Ebstein anomaly with mild morphological and functional abnormalities and better clinical profile, and the QRS duration is a marker of RV enlargement and dysfunction.

Fragmented Wide QRS on a 12-Lead ECG: A Sign of Myocardial Scar and Poor Prognosis

f-wQRS on a standard 12-lead ECG is a moderately sensitive and highly specific sign for myocardial scar in patients with known or suspected coronary artery disease and is also an independent predictor of mortality.

Absence and Resolution of Fragmented QRS Predict Reversible Myocardial Ischemia With Higher Probability of ST Segment Resolution in Patients With ST Segment Elevation Myocardial Infarction

FQRS was significantly related to infarction and myocardial reperfusion parameters before and after p-PCI and may be useful in identifying the patients at higher cardiac risk with increased ischemic jeopardized or infarcted myocardium and persistent or newly developed fQRS may predict low percent of ST segment resolution in patients undergoing p- PCI.

Electrophysiologic Characteristics of Ebstein's Anomaly of the Tricuspid Valve

Electrophysiologic characteristics of five patients with Ebstein's anomaly of the tricuspid valve were defined with studies using luminal intracardiac electrode catheters, finding the ARV was particularly irritable, and ventricular fibrillation was produced in two patients during catheter manipulation in this area.
