Long QT Syndrome

Overview

Specialists at Mayo Clinic have extensive experience evaluating, treating and counseling children and adults with long QT syndrome (LQTS). Mayo Clinic has also been a leader in research related to identifying people who are at greatest risk for sudden death related to long QT syndrome.

Each year, Mayo Clinic specialists evaluate more than 300 patients with long QT syndrome, making Mayo one of the most experienced centers in the world. The Long QT Syndrome Clinic and Sudden Death Genomics Laboratory at Mayo Clinic in Rochester have one of the most comprehensive programs internationally for families affected with this condition.

Diagnosis

Tests needed to diagnose LQTS vary with each individual. The diagnosis can sometimes be made from an electrocardiogram (ECG or EKG). Read more about long QT syndrome diagnosis.

Treatment Options

About Long QT Syndrome

Long QT syndrome (LQTS) is a rare, and sometimes fatal, heart rhythm disorder that is often present from birth. It gets its name from the peculiar pattern of the electrocardiogram (ECG or EKG) seen in people with the disease. It affects one person in every 5,000 to 7,000 people in the United States.
