Atrial fibrillation occurs when action potentials fire very rapidly within the pulmonary veins or atrium in a chaotic manner. The result is a very fast atrial rate — about 400 to 600 beats per ...

Frequently a precursor to stroke or heart failure, a heart condition known as atrial fibrillation, goes undetected until it has progressed to an advanced stage. But atrial fibrillation ...

Background Endurance exercise training produces multiple cardiac adaptations including changes in electrophysiological function that may make endurance-trained athletes more vulnerable to atrial ...

Just as in atrial fibrillation, not all of the P waves are able to conduct through the atrioventricular node, and thus the ventricular rate will not be as fast as the atrial rate. Typically ...

Atrial fibrillation is a common arrhythmia, and experts are interested in the relationship between atrial fibrillation and other conditions like dementia. Recent study results suggest that atrial ...
