Value of Fragmented QRS Complex on 12-lead ECG as A Valuable Marker of Myocardial Damage of CAD Patients

Majalah Kardiologi Indonesia, 2019
Background: Presence of Fragmented QRS (fQRS) on a 12-lead Electrocardiogram (ECG) was associated with various cardiac diseases. This phenomenon could represent as an electrical disruption of conduction system following myocardial damage due to coronary ...

ECG‐TransCovNet: A hybrid transformer model for accurate arrhythmia detection using Electrocardiogram signals

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.

Predicting adverse cardiovascular outcomes in post‐coronary artery bypass grafting patients using novel ECG frequency analysis of the QRS complex

Annals of Noninvasive Electrocardiology, 2021
Background A novel metric called Layered Symbolic Decomposition frequency (LSDf) has been shown to be an independent predictor of ventricular arrhythmia and mortality in patients receiving implantable cardioverter‐defibrillator (ICD) devices.

Fragmented QRS Complex: A Novel Marker of Cardiovascular Disease [PDF]

Clinical Cardiology, 2010
AbstractQRS complex fragmentation, defined as changes in QRS morphology with different RSR′ patterns: additional R waves, notched S wave, or > 1R′ wave, has recently been linked with various cardiac conditions and even been postulated to be predictive of outcomes in certain pathologies.

Agreement of the performance of equine electrocardiogram recording devices for ECG complexity analysis

Equine Veterinary Journal, EarlyView.
Abstract Background Non‐linear equine electrocardiography (ECG) analysis is an actively developing study area which has the potential to lead to novel, artificial intelligence‐based diagnostic tools in equine cardiology. As more ECG recording devices are becoming available, there is a need to ensure results are interchangeable regardless of the ...

Quantification of abnormal QRS peaks predicts response to cardiac resynchronization therapy and tracks structural remodeling.

PLoS ONE, 2019
BackgroundAlthough QRS duration (QRSd) is an important determinant of cardiac resynchronization therapy (CRT) response, non-responder rates remain high. QRS fragmentation can also reflect electrical dyssynchrony.

Pre‐anaesthetic risk assessment and management of dogs with myxomatous mitral valve disease: a spectrum of care narrative review

Journal of Small Animal Practice, EarlyView.
Myxomatous mitral valve disease, an acquired valvular degeneration, is the most common cardiac disorder in dogs, affecting approximately 10% of dogs in primary care veterinary practice. Dogs with myxomatous mitral valve disease frequently require anaesthesia for routine procedures.

Diffuse Fragmented QRS as an Index of Extensive Myocardial Scar

Indian Pacing and Electrophysiology Journal, 2010
A 70-year-old man with history of previous myocardial infarction was referred for cardiac resynchronization therapy (CRT) implantation. Echocardiography showed global wall motion abnormality and non-viable myocardium with ejection fraction of 15% and ...

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,
