Atrial fibrillation (AF) is an abnormal rhythm where atrial contractions are
ineffective and rapid and ventricular contractions are irregular. Often presented as
palpitation.
In valvular diseases this condition is caused by atrial dilatation and commonly
found in Mitral disease. Atrial fibrillation causes blood to stagnate in atria and can
cause clots in the atria.
This can lead to Thrombo-Embolism (Migration of small clots into the circulation
causing occlusion of arteries) It can embolize to legs or abdomen.
When it happens in the brain circulation, the result is a stroke! So AF is a serious
condition which needs to be treated. Patient has to be on Anticoagulant
medications (Blood thinning agents to prevent clots) until AF is reverted
