Ebstein Anomaly With QRS Fragmentation on Electrocardiogram

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. Abnormal conduction through the atrialized right ventricle leads to QRS fragmentation on electrocardiogram. Its presence suggests a more severe abnormality and a higher ri...

On the Algorithm for QRS Complexes Localisation in Electrocardiogram

Various techniques have been utilized in computer-assisted arrhythmia recognition for the management of cardiac disorders. To identify any arrhythmias characteristics, generally, the QRS complex is taken as a reference because the important amplitude. Several algorithms are developed to localise the R peaks. Most physiologic signal detection algorithms are based on preprocessing and deciding st...

Fragmented QRS Electrocardiogram - The Hidden Talisman?

Long-term prognosis of early repolarization with J-wave and QRS slur patterns on the resting electrocardiogram: a cohort study.

BACKGROUND The prognostic value of early repolarization with J waves and QRS slurs remains controversial. Although these findings are more prevalent in patients with idiopathic ventricular fibrillation, their ability to predict cardiovascular death has varied across studies. OBJECTIVE To test the hypothesis that J waves and QRS slurs on electrocardiograms (ECGs) are associated with increased ...

Effect of Cold Drinking on Electrocardiogram Waves

La localisation et le delai d'apparition de changement de l'onde (T) a la suite de l'ingestion des boissens froide laisse supposer que le refroidissement se propage par con­tiguiter et n 'intresse que les couches superficielle de l'epi­carde. Ce qui peut expliquer !'apparition de l'onde (T) faiblement negative dans les derivation D3 et avf.
