Arrhythmia

Watch this to learn about different types of irregular heart rhythms, signs and symptoms of an irregular heart rhythm, and how they are diagnosed.

Disorders in the heart's electrical system can lead to arrhythmias, or an abnormal heart rhythm. There are many types of arrhythmias and they're classified by where they occur in the heart and their pattern of abnormality. This segment will explain the arrhythmia known as Atrial Fibrillation.

Atrial fibrillation causes the heart to beat out of rhythm. To get the heart beating normally again, sometimes the heart is 'shocked' into normal rhythm. The idea of shocking the heart may be intimidating, but it's actually a quick and painless procedure.
