Arrhythmia is an umbrella term to describe a number of conditions where the muscle contraction of the heart is too slow, too fast or irregular because of a disturbance in the heart’s normal electrical activity.

Most arrhythmias just occur with no obvious cause. They can be due to genetic disorders or an acquired condition. Arrhythmias can range in severity from a minor inconvenience or discomfort to a potentially fatal problem. Atrial fibrillation is the most common form of sustained arrhythmia and can cause considerable disability and predispose a person to stroke.
