Atrial fibrillation (AF) is often found in patients with heart failure (HF). Clinical data indicated that the arrhythmic component of AF alone could contribute to left-ventricular (LV) dysfunction. However, the effects of non-tachycardic AF with arrhythmic excitation of the human LV, are ...

Atrial fibrillation (AFib) is a problem with your heart's electrical activity. With AFib, your heart quivers, beats irregularly, or skips beats. It can't pump blood through its chambers and out to your body as well as it should. Sometimes, blood can pool in the heart and form clots, ...
Atrial fibrillation affects the atria. Normally, the muscular walls of the atria contract at the same time, pumping blood into the lower two chambers (the ventricles). Then the walls of the ventricles contract at the same time, pumping blood to the rest of the body. ...
