Learn About Long QT Syndrome

What is the definition of Long QT Syndrome?
Long QT syndrome is a heart disorder characterized by rapid, irregular heartbeats caused by a signaling abnormality in the heart’s electrical system. The QT interval refers to the time it takes for the heart’s electrical system to make the ventricles of the heart contract and then recover. In long QT syndrome, there is a delay in the time it takes for the electrical system to recover between each heartbeat. This delay can cause rapid, irregular, and life-threatening ventricular contractions, also known as torsade de pointes.
What are the symptoms of Long QT Syndrome?
Some individuals with long QT syndrome may not have any symptoms. Symptoms of long QT syndrome include fainting, also called syncope, which may or may not be preceded by blurred vision, lightheadedness, palpitations, and weakness. In individuals with long QT syndrome, fainting may occur in response to being startled, excited, angry, or scared. Symptoms of long QT syndrome may also occur during sleep or when awakened suddenly. In some individuals, long QT syndrome may cause seizures. If the heart does not return to its normal rhythm after a long QT episode, cardiac arrest and sudden death may occur.

What are the current treatments for Long QT Syndrome?
Treatment for long QT syndrome depends on the type and location. Treatment for long QT syndrome is focused on preventing irregular heartbeats, cardiac arrest, and sudden death. Treatment for long QT syndrome may include lifestyle changes, such as avoiding intense exercise; medications, such as beta blockers and mexiletine; surgery, such as left cardiac sympathetic denervation or cardioverter-defibrillator implantation.

Comparing Direct and Indirect Methods for Cascade Screening in Familial Hypercholesterolemia (FH) and Long QT Syndrome (LQTS)

Summary: An important aspect of successful genomic medicine implementation is developing effective approaches for screening at-risk family members after probands are identified, also known as cascade screening. Most cascade screening studies conducted to date have been conducted outside the US, and very few studies have used a rigorous approach involving a comparator group or randomized controlled design. ...

A Phase 2/3, Two-part, Dose-ranging, Adaptive Study to Evaluate Efficacy and Safety of THRV-1268 in Participants Diagnosed With Long QT Syndrome Type 2 (LQTS 2)

Summary: The goal of this clinical trial is to learn whether the study drug THRV-1268 can safely and effectively shorten the QT interval in people diagnosed with Long QT Syndrome Type 2 (LQTS 2). The study will also learn about the safety and tolerability of THRV-1268 at different doses. The main questions this study aims to answer are: Does THRV-1268 reduce the QTc interval (a measure of the heart's elect...
