Evaluation of left atrial and ventricular remodeling in atrial fibrillation subtype by using speckle tracking echocardiography

Frontiers in Cardiovascular Medicine, 2023
BackgroundAtrial fibrillation (AF) is associated with cardiac structural and functional remodeling. We investigated the left atrial (LA) and left ventricular (LV) changes in AF subtypes by using two-dimensional echocardiography strain techniques ...

A preliminary assessment of the effects of ATI-2042 in subjects with paroxysmal atrial fibrillation using implanted pacemaker methodology [PDF]

, 2009
Aims ATI-2042 (budiodarone) is a chemical analogue of amiodarone with a half life of 7 h. It is electrophysiologically similar to amiodarone, but may not have metabolic and interaction side effects.

Contribution of the respiratory rhythm to sinus arrhythmia in normal unanesthetized subjects during positive-pres sure mechanical hyperventilation

, 2004
The precise contribution of the CO2-dependent respiratory rhythm to sinus arrhythmia in eupnea is unclear. The respiratory rhythm and sinus arrhythmia were measured in 12 normal, unanesthetized subjects in normocapnia and hypocapnia during mechanical ...

Atrial Imaging and Cardiac Rhythm in Cryptogenic Embolic Stroke: The ARIES Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Unknown cardioembolic sources are frequent causes of cryptogenic stroke. We analyzed the risk of atrial fibrillation (AF) or high burden of ectopic atrial activity (HBEA) in patients with cryptogenic stroke, assessing atrial function and 1 ...

Cardiac Device Algorithms for Optimal Outcomes in Patients with Sick Sinus Syndrome [PDF]

, 2013
Sick sinus syndrome (SSS) is a relatively common chronic condition affecting the electrical conduction system of the heart. In the absence of any reversible cause of SSS, the most effective treatment is implantation of a permanent pacemaker to maintain ...

Predicting of Long-term Maintenance of Sinus Rhythm after Cardioversion in Patients with Nonvalvular Persistent Atrial Fibrillation

, 2014
Introduction. The choice of the optimal strategy for conducting the patients with persistent atrial fibrillation (AF) and the expediency of prolonged antiarrhythmic treatment after cardioversion is highly dependent on the probability of relapse of ...
