How to Treat Long Qt Syndrome?

What is Long QT Syndrome (LQTS)?

Long QT Syndrome (LQTS) is a heart rhythm disorder marked by a delayed reset of the heart's electrical system between beats, reflected in the QT interval on an electrocardiogram (ECG). Dysfunction in ion channels can cause this delay, leading to a prolonged QT interval and an increased risk of life-threatening ventricular tachycardia, known as Torsades de Pointes. This disruption in heart electrical activity may result in arrhythmias, fainting, seizures, or sudden cardiac arrest. Timely detection and management are crucial for minimizing the risk of severe events and promoting overall cardiac health.

Why Does Long QT Syndrome Occur?

Long QT Syndrome is primarily a genetic disorder, with mutations in certain genes affecting the ion channels responsible for regulating the heart's electrical activity. These mutations disrupt the normal flow of ions, leading to an imbalance and the characteristic prolonged QT interval. In some cases, Long QT Syndrome may also be acquired through certain medications, electrolyte imbalances, or other medical conditions.

How Does Long QT Syndrome Manifest?

The manifestations of Long QT Syndrome can vary, ranging from no symptoms to life-threatening arrhythmias. Common symptoms include fainting (syncope), seizures, and palpitations. Triggers for arrhythmias may include exercise, emotional stress, or loud noises. Unfortunately, the first sign of Long QT Syndrome for some individuals may be sudden cardiac arrest, emphasizing the importance of early detection and intervention.
