Cardiac Arrhythmias

The beating of your heart is very organized, taking its cue from a built-in electrical system. A normal heart rate is regular, at 60 to 100 beats per minute. An arrhythmia is any kind of abnormal heartbeat—too fast, too slow, or irregular. This video explains different arrhythmias and what you should do if you have one.
