Medication
Long QT syndrome. For people with LQTS who survive cardiac arrest and remain untreated, the risk of death within 15 years is greater than 50%. With proper treatment this decreases to less than 1% over 20 years.
Procedures
- Antibiotics – macrolides, fluoroquinolones, trimethoprim-sulfa
- Antifungals – some azole antifungals
- Antihistamines – terfenadine and astemizole have been withdrawn from the market because of this risk
- Antiemetics and promotility agents – ondansteron, phenergen, cisapride
- Cough/cold medications – pseudoephedrine
- Stimulant medications – methylphenidate
Self-care
Long QT syndrome (LQTS) is an arrhythmogenic disorder characterized by repolarization abnormalities with a tendency to cause life threatening cardiac events. The first manifestation of the syndrome may be sudden death, therefore, early diagnosis and therapy is of great importance. LQTS can be congen …

Can long QT syndrome be cured?
There's no cure for LQTS. Instead, treatment usually involves reducing your risk of developing a heart arrhythmia by: taking medications called beta blockers to reduce too fast heart rhythms. avoiding medications known to prolong QT interval.
What is definitive treatment for long QT syndrome?
Beta blockers. These heart drugs are standard therapy for most patients with long QT syndrome. They slow the heart rate and make long QT episodes less likely. Beta blockers used to treat long QT syndrome include nadolol (Corgard) and propranolol (Inderal LA, InnoPran XL).
When should I worry about prolonged QT?
A prolonged QT interval is typically defined in adults as a corrected QT interval exceeding 440 ms in males and 460 ms in females on resting electrocardiogram (ECG). We worry about QT prolongation because it reflects delayed myocardial repolarization, which can lead to torsades de pointes (TdP).
Is long QT syndrome serious?
Long QT syndrome (LQTS) is an abnormal feature of the heart's electrical system that can lead to a potentially life-threatening arrhythmia called torsades de pointes (pronounced torsad de pwant). Torsades de pointes may result in syncope (fainting) or sudden cardiac death.
Can you live a normal life with long QT?
What happens if it is not treated? LQTS is usually a lifelong condition. The risk of having an abnormal heart rhythm that leads to fainting or cardiac arrest may lessen as you get older, especially in men after age 40. However, the risk never completely goes away.

Can anxiety cause long QT syndrome?
General anxiety, depression (HADS), physical health (PCS), and heart-focused anxiety (CAQ-avoidance, -attention and -fear) scores of individuals with familial Long QT syndrome (LQTS) as compared to individuals with familial Hypertrophic cardiomyopathy (HCM).
How do I fix my QT interval?
Corrected QT interval (QTc)Bazett formula: QTC = QT / √ RR.Fridericia formula: QTC = QT / RR. 1/3Framingham formula: QTC = QT + 0.154 (1 – RR)Hodges formula: QTC = QT + 1.75 (heart rate – 60)
Does long QT show on ECG?
An ECG records your heart's rhythm and electrical activity. If you have long QT syndrome, the trace of the QT section (showing part of the heartbeat) will be longer than normal. Sometimes an exercise ECG will be needed to confirm the diagnosis.
How does long QT feel?
Symptoms of long QT syndrome include: Fainting (syncope), which can occur when the heart isn't pumping enough blood to the brain. Irregular heart rhythm (arrythmia) during sleep. Heart palpitations, which feel like fluttering in the chest.
Does long QT make you tired?
What happens if I develop Long QT syndrome? Even when an ECG shows a long QT interval, many people never have severe heart problems and are able to live a normal life. However, some people develop symptoms, such as fainting, dizziness, fatigue, and heart palpitations.
Can you drive with long QT syndrome?
You must not drive if you've suffered from: loss of consciousness or fainting. another cardiovascular condition that might affect your ability to drive safely - you must check with your doctor before you drive.
