Atrial Fibrillation is an abnormal rhythm of the heart characterized by quivering instead of normal beating. This decreases the efficiency of the heart to move blood increasing the incidence of stroke because of the formation of blood clots in the heart.


Electrocardiogram(ECG) measures electrical impulses of the heart. Holter Monitor records electrical activity of the heart as you do your daily activities. Echocardiogram provides video images of the heart in motion to detect any structural heart disease. Blood tests to help rule out other conditions leading to atrial fibrillation.


Treatments include medications and procedures that aim to reset the heart rhythm to normal or control the heart rate and to prevent blood clot formation. Medications include blood thinners, cardioversion drugs, and anti-arrhytmics to help prevent future episodes of atrial fibrillation. If medications and cardioversion techniques won't work to control atrial fibrillation surgical and catheter interventions are carried out.
