OVERVIEW | SYMPTOMS | DIAGNOSIS | TREATMENT
Any irregularity in your heart's natural rhythm is called an arrhythmia. Almost everyone's heart skips
or flutters at one time or another, and these mild, one-time palpitations are harmless. But there are about 4 million Americans who have recurrent arrhythmias, and these people should be under the care of a doctor.

There are two categories of arrhythmias:
- Ventricular arrhythmias - Happen in the heart's two lower chambers, called the ventricles.
- Supraventricular arrhythmias - Happen in the structures above the ventricles, mainly the atria, which are the heart's two upper chambers.
Arrhythmias are further defined by the speed of the heartbeats:
- Bradycardia - A very slow heart rate when the heart rate is less than 60 beats per minute.
- Tachycardia - A very fast heart rate when the heart beats faster than 100 beats per minute.
- Fibrillation - The most serious form of arrhythmia, is fast, uncoordinated beats, which are contractions of individual heart-muscle fibers.
