Does Long QT cause fast heart rate?
What is long QT syndrome? Long QT syndrome (LQTS) is a disease that can cause a dangerous rapid heart rate and irregular rhythm involving the bottom pumping chambers of the heart (ventricles).
What does prolonged QT feel like?
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.
When should I be concerned about long QT?
Signs and symptoms of Long QT Syndrome Fainting, especially as a result of acute emotions (such as anger or surprise), exercise, menses (menstruation), or swimming in cold water. Seizures. Ventricular arrhythmias (abnormal heart rhythms originating in the lower chambers) Sudden cardiac arrest.
Is long QT syndrome an arrhythmia?
Long QT syndrome (LQTS) is heart signaling disorder that can cause fast, chaotic heartbeats (arrhythmias). A heart signaling disorder is also called a heart conduction disorder. Some people are born with altered DNA that causes long QT syndrome (congenital long QT syndrome).
Does Long QT get worse with age?
QTc generally increases with age, and age-related electrophysiological and structural changes may increase the risk of potentially life-threatening arrhythmic events.
How does Long QT cause sudden death?
The ventricles beat more than 200 times per minute, resulting in a sudden drop in blood pressure. Though it often stops on its own, torsades de pointes that persists can lead to ventricular fibrillation, which may cause sudden cardiac death.
Can you live a long 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.
