Research

Mayo Clinic researchers actively study new ways to detect, diagnose, and treat long QT syndrome and other causes of sudden death. Mayo's research team has extensively studied the genetics of long QT syndrome. Recent research topics have included using artificial intelligence and remote ECG monitoring for long QT syndrome.
