Rapid ventricular rate or response (RVR) AFib is caused by abnormal electrical impulses in the atria , which are the upper chambers of the heart. These chambers fibrillate, or quiver, rapidly. The result is a rapid and irregular pumping of blood through the heart.
Read moreWhat is the fibrillation?
Definition of fibrillation 1 : an act or process of forming fibers or fibrils . 2a : a muscular twitching involving individual muscle fibers acting without coordination. b : very rapid irregular contractions of the muscle fibers of the heart resulting in a lack of synchronism between heartbeat and pulse.
Read moreWhat happens during a fibrillation?
During atrial fibrillation, the heart’s upper chambers (the atria) beat chaotically and irregularly — out of sync with the lower chambers (the ventricles) of the heart . For many people, A-fib may have no symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness.19 Eki 2021
Read moreWhat is the difference between fibrillation and arrhythmia?
Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively . It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age.
Read moreWhat is fibrillation caused by?
The basic cause of AFib is disorganized signals that make your heart’s two upper chambers (the atria) squeeze very fast and out of sync . They contract so quickly that the heart walls quiver, or fibrillate. Damage to your heart’s electrical system can cause AFib.

Amongst the group of patients aged between 55-74 years, the 10 year mortality was 61.5% in men with AF compared to 30% in men without AF . Amongst women in a similar age group, the 10 year mortality was 57.6% in the AF group versus 20.9% in women without AF.

If an irregular rhythm, or atrial fibrillation, is triggered by an OTC preparation, it may persist for some period of time. But generally, it goes away on its own .
