Arrhythmia, also known as an irregular heartbeat, is a condition in which the heart beats too fast, too slow, or with an irregular pattern. It is a common condition, affecting millions of Americans.

While arrhythmia can be benign and cause no symptoms, it can also be life-threatening. If you have an arrhythmia, you may experience symptoms such as shortness of breath, chest pain, dizziness, or fainting.

Arrhythmia is caused by a variety of factors, including abnormal heart structures, electrolyte imbalances, and medications.

Treatment for arrhythmia often involves medication or electrical cardioversion. In some cases, surgery may be necessary to correct the underlying cause of the arrhythmia.
