The goal of treatment for long QT syndrome (LQTS) is to prevent dangerous arrhythmias. Treatment does not cure LQTS.

Long QT Syndrome Treatment Options

LQTS can be treated with medicines, like beta-blockers. These slow the heart rate and help the heart deliver more blood. They can also decrease the chance of having dangerous heart rhythms and sudden cardiac arrest.

Some children with LQTS may need a defibrillator. Read more about these devices in our Arrhythmia Program.

Your doctor may also want your child to avoid things that might trigger an arrhythmia. This varies by child, so talk with your doctor about it.

Triggers may include strenuous exercise, certain medicines, conditions that can lower potassium (like diarrhea and vomiting) and loud noises that might startle them during sleep. Ask your doctor how to deal with your child’s possible triggers.
