LQT3

LQT3 (Long QT Syndrome Type 3) is a genetic condition affecting the heart's electrical system, which can cause irregular, potentially dangerous heart rhythms. It results from mutations in the SCN5A gene, leading to abnormal sodium channels that delay the heart's recovery after each beat, lengthening the time between heartbeats (the QT interval). This prolonged interval increases the risk of sudden dizziness, fainting, or even sudden cardiac arrest, especially during stress or sleep. While it can be managed with medication or devices, awareness and proper treatment are crucial to reduce risks.
