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.

The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation [PDF]

, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...

A novel approach to terminate roof-dependent atrial flutter with epicardial conduction through septopulmonary bundle

BMC Cardiovascular Disorders
Atrial flutter, a prevalent cardiac arrhythmia, is primarily characterized by reentrant circuits in the right atrium. However, atypical forms of atrial flutter present distinct challenges in terms of diagnosis and treatment.

Mechanisms of atrial flutter following epicardial high intensity focused ultrasound left atrial ablative procedures during concomitant cardiac surgery

The Egyptian Heart Journal, 2014
Introduction: Iatrogenic atrial tachyarrhythmias have increased with the widespread application of left atrial ablative procedures to treat atrial fibrillation. Methods and results: Entrainment and activation mapping were utilized to study the mechanisms

Elevated cardiovascular risk associated with hormone replacement therapy: A comprehensive analysis of reproductive factors and atherosclerotic cardiovascular disease outcomes in the UK Biobank cohort

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Among 170,250 UK Biobank women (2006–2024), ever HRT use was associated with higher incident ASCVD risk (adjusted HR 1.13, 95% CI 1.08–1.18), largely driven by ischemic stroke. Associations were stronger in women ≤45 years and during perimenopause. Mediation via sex hormones, inflammatory markers, or lipids was minimal (<2%).

Catheter ablation of typical right atrial flutter in a 20‐day‐old neonate with tachycardiomyopathy

Journal of Arrhythmia
Background Fetal echocardiography can diagnose neonatal atrial flutter, which can cause heart failure in newborns. Little is known about catheter ablation in this population.

A new animal model of atrial flutter [PDF]

, 1986
A new, simple and reliable model of atrial flutter utilizing postpericardiotomy pericarditis was developed in the dog. Using a sterile technique, the pericardium was opened by way of a right thoracotomy, Teflon-coated, stainless steel wire electrodes ...

Atrial flutter

, 2021
El término «flutter auricular» se describió por primera vez en 1886 en animales como una actividad eléctrica auricular rápida y regular, y en 1911 se describieron sus características electrocardiográficas con una actividad en forma de «dientes de sierra»,
