Kids who are experiencing heart rhythm problems (arrhythmias) need precise, accurate diagnoses as soon as possible. At Atrium Health Levine Children’s, we use state-of-the-art electrophysiology techniques to pinpoint the cause of your child’s arrhythmia – and, in most cases, to fix it.

Electrophysiology is a branch of medicine where doctors investigate heart arrhythmias by studying the heart’s electrical pulses. Electrophysiology procedures can also be used to correct abnormal electrical pulses that cause heartbeat abnormalities.

Electrophysiology studies and treatments

Electrophysiology studies

An electrocardiogram (ECG) is the most commonly ordered medical test and is often the first step in evaluating your child’s heart.

If an arrhythmia is discovered, an electrophysiology study is often the next step in evaluating your child’s heart rhythm. For this test, our doctors insert a catheter – a long, thin tube equipped with electrodes to measure electricity – into a vein in the neck and groin. Then we guide the catheter into the heart to record electrical signals. This helps us understand each child’s heart rhythm and how it functions. Our team can also do more detailed evaluations like:

  • Implantable loop recordings: A standard electrophysiology study may not collect enough data to help us understand complex conditions. In that case, we can use a minimally invasive procedure to install tiny devices to monitor the heart. These devices take implantable loop recordings that record heart activity for months or even years, giving us vital information that we need to diagnose and treat your child.
  • Metabolic stress testing: We use these tests to closely monitor your child’s heart while they exercise on a treadmill or stationary bike. This shows us how the heart and lungs work under stress and helps us understand if symptoms like shortness of breath are a result of illness or poor physical fitness.
  • Speckle-tracking echocardiography: This gives doctors additional information about how the heart’s ventricles function. We’re the only pediatric team in our region that offers this advanced tool.

New technology helps patients avoid radiology, surgery and medication

Atrium Health Levine Children’s houses the first lab in the region that uses a highly precise electrophysiology tool called “the Grid.” Learn how the Grid can cure problems like arrhythmias in less time and with fewer side effects.
