Long QT Syndrome is an electrical heart condition. It is an arrhythmia. This is a fancy way to say that the rhythm of the heart gets interrupted.

There name, which lacks creativity, actually reveals the problem. The waves on an electrocardiogram (ECG) are named P, Q, S and T. When the line between Q and T is a little too long, it suggests that the heart is not recharging quickly enough. Hence, you’ve got Long QT.

Most people with Long QT are treated with a beta blocker and need to make lifestyle changes. More serious conditions require medical intervention, like an implantable cardioverter defibrillator (ICD).
