James Oujiri, MD, electrophysiologist, describes the symptoms of arrhythmia, or irregular heartbeat. Dr. Oujiri also talks about when you should seek treatment and treatment options.

An arrhythmia, or dysrhythmia, is an irregular heartbeat or abnormal heart rhythm. Arrhythmias can cause the heart to pump less effectively.

Arrhythmias happen when the heart's electrical system, which regulates its pumping action, sends faulty signals to the heart muscle. An irregular heartbeat can be harmless or life-threatening, so proper diagnosis and treatment is essential.

With a few exceptions, all arrhythmias are treatable. This is especially true in our program, where leading arrhythmia experts specialize in treating complex abnormal heart rhythm problems associated with prior heart surgery, congenital heart disease, coronary blockages and heart attack.

Arrhythmia Physician Specialists

The multidisciplinary team includes board-certified electrophysiologists (cardiologists who specialize in the electrical activity of the heart and the diagnosis and treatment of heart rhythm disorders), cardiac surgeons and other heart and vascular specialists. Their combined skills and experience make it possible to successfully treat even the most complex cases of arrhythmia. These cases might include patients who have complicated conditions with multiple diagnoses.

Complete Diagnostic Capabilities

Many techniques are used to determine the cause of an abnormal heart rhythm, whether bradycardia (a slow heart rate), tachycardia (a rapid heart rate), atrial fibrillation (an irregular heartbeat) or one of the many other heart rhythm disorders.

We offer the full spectrum of state-of-the-art diagnostic tests, including electrophysiology studies, cardiac MRI, genetic testing, event monitors and tilt table tests.

Comprehensive Treatment Options

As part of an academic medical center, our physicians use the latest technology and research results to provide the most advanced treatments for atrial fibrillation.

Research Leaders

Our heart and vascular physicians conduct and participate in local and national research studies and clinical trials related to arrhythmia and other heart and vascular conditions. See our complete list of clinical research related to heart and vascular disease.

Expert Care for All Types of Arrhythmia Conditions

There are many types of arrhythmias and disorders related to arrhythmias, so careful diagnosis and treatment planning is required. Whether atrial fibrillation, ventricular tachycardia (VT), paroxysmal supraventricular tachycardia (PSVT) or other dysrhythmia, our Arrhythmia Program electrophysiologists and other physician specialists have the expertise to meet each patient’s care needs.
