A number of medical offices care for the more common types of arrhythmia and offer basic therapies like medications or pacemakers. But we offer a comprehensive range of services for all arrhythmias — including those associated with complex congenital heart disease

Our program features:

  • Established experience: Our arrhythmia doctors (electrophysiologists) have a long track record of treating complex arrhythmias, including atrial fibrillation, atrial tachycardia and ventricular tachycardia. Accurately diagnosing arrhythmia requires a developed sense of clinical judgment and practice. 
  • World-leading imaging: We are world-recognized for incorporating 3D imaging into treatment planning for complex arrhythmias like ventricular tachycardia (v-tach). Learn more about our 3D imaging and v-tach ablation.
  • Pediatric Care: Our center is one of the few in the region with an electrophysiologist specializing in pediatric care. 
  • Dedicated labs: Unlike many medical offices that offer limited arrhythmia care, we have electrophysiology labs where we provide the full range of tests and treatments, including second opinions. In addition to inpatient care, we offer outpatient practices in several locations. Learn more about our EP labs.

What is an Arrhythmia?

Occasionally your heart skips a beat, beats rapidly or flutters. This is often a random, momentary glitch. But it can also represent an irregular heart rhythm, a condition called arrhythmia.

Arrhythmias are fairly common, especially as you age. Many are not worrisome. But others can cause symptoms and interfere with your daily activities. Some can even trigger stroke or the sudden loss of heart function, known as cardiac arrest. Arrhythmias are the leading cause of sudden cardiac death, with 400,000 victims a year.

Heart Arrhythmia Types

There are three types of arrhythmias, based on how the heart is beating:

  • Too slowly (bradycardia): less than 60 beats per minute
  • Too rapidly (tachycardia): more than 100 beats per minute
  • Erratically (fibrillation)

Our electrophysiology team treats the full spectrum of arrhythmias, including those that are less common or less likely to cause serious problems — though complications are still possible from some if left untreated. These include:

Diagnosing Arrhythmia

At the University of Maryland Heart and Vascular Center, our patients have access to the very latest diagnostic technology and doctors who have spent years refining the clinical judgment needed to make the right evaluation. Learn more about cardiac diagnosis

Our doctors will confirm or rule out the possibility of an arrhythmia and its suspected causes. We offer this service in two fully equipped electrophysiology (EP) exam suites — one of the few centers in the region to offer such a specialized, comprehensive facility. Learn more about our EP labs.

Arrhythmia Treatment

Many arrhythmias do not require treatment, while others may only require a lifestyle change or medications such as anti-arrhythmia drugs.

But some arrhythmias require more direct intervention. Learn more about our treatment options:
