Cardiac arrhythmia is an irregularity of the heart beat that causes the heart to beat too slowly, too fast, or irregularly. An abnormally fast heart rate is called tachycardia and an abnormally slow heart rate is called bradycardia.
There are different types of arrhythmias. Most arrhythmias are not particularly dangerous. However, some may be life threatening and do require immediate medical attention. During arrhythmias, the heart may not be able to pump enough blood to the body and lack of blood flow can damage the brain, heart, and other organs.
