Heart Arrhythmias

What is a Heart Arrhythmia?

A heart arrhythmia refers to an irregular heartbeat, whether your heartbeat is too fast, too slow or has an irregular rhythm.

A heartbeat that is too fast is called tachycardia (TAK-ih-KAR-de-ah). A heartbeat that is too slow is called bradycardia (bray-de-KAR-de-ah).

Although arrhythmias are considered harmless, certain arrhythmias can be serious or even life threatening. Depending on the arrhythmia, the heart may not be able to properly pump blood throughout the body. Lack of blood flow can cause damage to major organs, including the brain, heart and other organs.
