Long QT syndrome care at Mayo Clinic

Your Mayo Clinic care team

Mayo Clinic has one of the largest dedicated long QT syndrome specialty clinics in the United States. In the Heart Rhythm Clinic, Mayo Clinic health care providers work together to evaluate and treat people with a wide variety of heart rhythm disorders.

Mayo Clinic doctors trained in heart conditions (cardiologists), doctors trained in treating children with heart conditions (pediatric cardiologists), heart rhythm specialists (electrophysiologists) and heart surgeons (cardiovascular surgeons) provide coordinated, comprehensive care for people who have long QT syndrome. This collaborative approach means care providers can often evaluate you and develop a treatment plan within two or three days.

  • Individualized approach. Health care providers at Mayo Clinic provide care for you as a whole person. They take the time to get to know you and work with you to provide exactly the care you need. Mayo care providers evaluate each person's condition and establish an individualized treatment program.
  • Advanced diagnosis and treatment. At Mayo Clinic, you will have access to the latest imaging and diagnostic tools. Mayo cardiovascular surgeons have experience performing minimally invasive left cardiac sympathetic denervation surgeries to treat long QT syndrome.
  • Innovative research. Providers in Mayo Clinic's Cardiovascular Research Center are focused on developing diagnostic tests and innovative treatments for people with cardiovascular disease.
