Automated differentiation of wide QRS complex tachycardia using QRS complex polarity [PDF]

open access: yesCommunications Medicine
Background Wide QRS complex tachycardia (WCT) differentiation into ventricular tachycardia (VT) and supraventricular wide complex tachycardia (SWCT) remains challenging despite numerous 12-lead electrocardiogram (ECG) criteria and algorithms.

Relationship Between Fragmented QRS Complex and Left Ventricular Fibrosis and Function in Patients With Danon Disease [PDF]

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundFragmented QRS (f-QRS) complex on the surface ECG is a cardiac conduction abnormality that indicates myocardial scarring. The relationship between the f-QRS complex and cardiac status in patients with Danon disease (DD) remains unclear and will

A simple and effective deep neural network based QRS complex detection method on ECG signal [PDF]

open access: yesFrontiers in Physiology
Introduction: The QRS complex is the most prominent waveform within the electrocardiograph (ECG) signal. The accurate detection of the QRS complex is an essential step in the ECG analysis algorithm, which can provide fundamental information for the ...

Retrospective evaluation of notched and fragmented QRS complex in dogs with naturally occurring myxomatous mitral valve disease [PDF]

open access: yesVeterinary Quarterly, 2021
Myxomatous mitral valve disease (MMVD) is the most common cardiac disease in dogs. The association of QRS notching (nQRS) or fragmentation (fQRS) with disease severity is currently unknown.

Spatial distribution of physiologic 12-lead QRS complex [PDF]

open access: yesScientific Reports, 2021
The normal physiologic range of QRS complex duration spans between 80 and 125 ms with known differences between females and males which cannot be explained by the anatomical variations of heart sizes. To investigate the reasons for the sex differences as

Predictive value of QRS complex duration in patients with chronic heart failure and atrial fibrillation: retrospective study [PDF]

open access: yesТерапевтический архив, 2022
Aim. To study of the features of the clinical course and prognosis in patients with chronic heart failure with low ejection fraction (HFrEF) and atrial fibrillation (AF) depending on the width of the QRS complex. Materials and methods.

Identity Recognition Based on the QRS Complex Dynamics of Electrocardiogram

open access: yesIEEE Access, 2020
Biometric identification based on electrocardiogram signals has attracted increasing attention. As the most dominant feature of the electrocardiogram signal, the QRS complex(i.e., the combination of ECG Q, R, and S waves) has been used for identification

Narrow QRS complexes intervening wide QRS complexes [PDF]

open access: yesNetherlands Heart Journal, 2012
An 80-year-old male was admitted to our hospital with complaints of palpitations. He was diagnosed with atrial fibrillation that stopped spontaneously one hour after admission (not shown). Before he was discharged the following ECG was recorded. How would you judge this ECG (Fig. 1) and, in particular, how would you explain the occurrence of narrow QRS

Accurate Fetal QRS-Complex Classification from Abdominal Electrocardiogram Using Deep Learning

open access: yesInternational Journal of Computational Intelligence Systems, 2023
Fetal heart monitoring during pregnancy plays a critical role in diagnosing congenital heart disease (CHD). A noninvasive fetal electrocardiogram (fECG) provides additional clinical information for fetal heart monitoring.
