Learn About Long QT Syndrome 3

What is the definition of Long QT Syndrome 3?

Long Q-T syndrome 3 (LQT3) is a rare disorder of the heart’s electrical system that can be congenital (present at birth) or acquired. In long Q-T syndrome 3, there is a defect in ion channels in the cells of the heart, causing a delay in how long it takes for the heart’s electrical system to recharge after each heartbeat. The Q-T interval on an electrocardiogram (ECG) represents the time it takes for the heart’s electrical system to fire an impulse through the heart’s ventricles and then recharge; in other words, how long it takes for the heart muscle to contract and then recover. In long Q-T syndrome 3, the 3 refers to the type of ion channel that is affected.

What are the symptoms of Long QT Syndrome 3?

Some individuals with congenital long Q-T syndrome 3 may not have any symptoms. Symptoms of congenital long Q-T syndrome 3 usually appear in the teen years through the 20s. Symptoms of long Q-T syndrome 3 may include fainting (syncope), seizures, abnormal heart rhythms (arrhythmias), palpitations, ventricular tachycardia (rapid heartbeat), and sudden cardiac death. Symptoms of long Q-T syndrome 3 commonly occur after exercise, after being startled or emotional overexcitement, during sleep, or upon suddenly waking up.

What are the current treatments for Long QT Syndrome 3?

Treatment for long Q-T syndrome 3 is focused on alleviating symptoms and preventing sudden cardiac death and may include medications, such as beta blockers (nadolol and propranolol), surgery that interrupts the nerves to the heart (sympathectomy), the use of an implantable automatic cardioverter-defibrillator (ICD), and avoiding triggering events.
