Managing long QT syndrome in daily life primarily involves avoiding known triggers that can cause dangerous arrhythmias. Individuals with LQTS are advised to avoid medications that prolong the QT interval, as these can worsen their condition. Healthcare providers often provide patients with a list of medications to avoid and may recommend alternatives if necessary. Additionally, managing stress and limiting intense physical activities, particularly competitive sports, can reduce the risk of sudden arrhythmic episodes, especially in individuals with specific types of LQTS where exercise or emotional excitement is a known trigger.

Monitoring heart health with regular check-ups and ECGs is another critical aspect of daily management. For some individuals, wearing a medical alert bracelet can be helpful in the event of an emergency, ensuring that healthcare providers are aware of their condition. In cases where an implantable cardioverter defibrillator (ICD) is recommended, individuals may need to learn how to live with and maintain this device, which is designed to correct dangerous arrhythmias automatically. With careful management and regular medical oversight, most people with LQTS can live normal, active lives while minimizing their risk of complications.
