Long QT Syndrome, An Issue of Cardiac Electrophysiology Clinics

Long QT syndrome is a heart rhythm disorder that can cause fast, chaotic heartbeats. In some cases, long QT syndrome can cause sudden death. Long QT syndrome may result from a genetic mutation or be caused by certain medications and medical conditions. The condition is treatable with medication, surgery, or an implantable device. Because it may have serious consequences, it's important for electrophysiologists to know about long QT syndrome.
