Arrhythmia is a complication with the rate of your heartbeat. It arises with the improper working of electrical impulses that correlate with your heartbeats, affecting your heart to beat too slow, too fast or irregularly. When the rate is too slow, it is called bradycardia. When the rate is too fast, it is called tachycardia. Many factors such as smoking, congenital heart defects and stress are majorly responsible for this condition. There are many effective treatments available that focus to recondition a normal heart rhythm.
