Cardiac Arrhythmia Services

Abnormal heart rhythms, also known as cardiac arrhythmias, occur when the electrical impulses that keep your heart beating steadily go awry. They can be alarming to experience.

Arrhythmias are usually harmless, though some can be life-threatening. They also are common, affecting nearly four million Americans.

The cardiac arrhythmia specialists at UC Irvine Health have access to one of the most advanced electrophysiology labs in Orange County, which can help pinpoint why your heart isn't beating normally.

Armed with this information, our world-class cardiologists will develop a treatment plan that fits your unique needs.

We see patients at UC Irvine Medical Center in Orange and at UC Irvine Health Gottschalk Medical Plaza on the university campus in Irvine.
