Outcomes Associated With Oral Anticoagulants Plus Antiplatelets in Patients With Newly Diagnosed Atrial Fibrillation. [PDF]

, 2020
Importance: Patients with nonvalvular atrial fibrillation at risk of stroke should receive oral anticoagulants (OAC). However, approximately 1 in 8 patients in the Global Anticoagulant Registry in the Field (GARFIELD-AF) registry are treated with ...

Physiological Assessment of Ventricular Myocardial Voltage Using Omnipolar Electrograms

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundCharacterization of myocardial health by bipolar electrograms are critical for ventricular tachycardia therapy. Dependence of bipolar electrograms on electrode orientation may reduce reliability of voltage assessment along the plane of ...

Atrial Fibrillation and Myocardial Infarction: A Systematic Review and Appraisal of Pathophysiologic Mechanisms [PDF]

, 2016
A growing body of evidence suggests that atrial fibrillation (AF) is associated with myocardial infarction (MI). However, incidence and management of MI in AF is still undefined. METHODS AND RESULTS: We searched MEDLINE via PubMed and Cochrane database

Amyloid fibril formation kinetics of low-pH denatured bovine PI3K-SH3 monitored by three different NMR techniques

Frontiers in Molecular Biosciences, 2023
Introduction: Misfolding of amyloidogenic proteins is a molecular hallmark of neurodegenerative diseases in humans. A detailed understanding of the underlying molecular mechanisms is mandatory for developing innovative therapeutic approaches.

Detection of atrial fibrillation episodes in long-term heart rhythm signals using a support vector machine [PDF]

, 2020
Atrial fibrillation (AF) is a serious heart arrhythmia leading to a significant increase of the risk for occurrence of ischemic stroke. Clinically, the AF episode is recognized in an electrocardiogram.

Atrial Fibrillation Degenerates Into Ventricular Fibrillation

Journal of the American College of Cardiology, 2010
![Figure][1] A 43-year-old man with paroxysmal atrial fibrillation (AF) and an implantable cardioverter defibrillator (ICD) placed for documented ventricular fibrillation (VF), presented with an ICD shock. Ventricular pre-excitation was not present.

The Value of Voltage Histogram Analysis Derived Right Atrial Scar Burden in the Prediction of Left Atrial Scar Burden

Cardiology Research and Practice, 2020
Introduction. Growing evidence suggests that fibrotic changes can be observed in atrial fibrillation (AF) in both atria. Quantification of the scar burden during electroanatomical mapping might have important therapeutic and prognostic consequences ...

Extinction Dynamics of Cardiac Fibrillation [PDF]

, 2018
During episodes of atrial fibrillation, the heart's electrical activity becomes disorganized and shows fragmenting spiral waves. To systematically address how this pattern terminates using spatially extended simulations exceeds current computational ...

Focal impulse and rotor modulation of atrial rotors during atrial fibrillation leads to organization of left atrial activation as reflected by waveform morphology recurrence quantification analysis and organizational index

Journal of Arrhythmia, 2020
Background Focal impulse and rotor modulation (FIRM) can cause slowing, organization, and occasionally termination of atrial fibrillation (AF), although results have been mixed.

The effects of 4,6-Dichloro-2-Sodiooxy-1,3,5-Triazine on the Fibrillation Propensity of Lyocell Fibers

Journal of Natural Fibers, 2023
Dichlorotriazine reactive crosslinker has been used to reduce the fibrillation of Lyocell. The fibrillation propensity and mechanism of 4, 6-dichloro-2-sodium dioxy-1, 3, 5-triazine treatment on Lyocell fibers were studied, and the mechanical properties ...
