LQTstands forLong QT syndrome
Full Form of LQT
What is LQT?
Long QT syndrome (LQT) is a heart condition that affects the electrical system of the heart, specifically the repolarization phase of the cardiac cycle. It is characterised by a prolonged QT interval on an electrocardiogram (ECG), which indicates delayed ventricular repolarisation and increases the risk of life-threatening arrhythmias such as torsades de pointes. In India, LQT is increasingly recognised in cardiology clinics, particularly among young adults and children presenting with syncope, palpitations, or a family history of sudden cardiac death. The condition can be congenital, caused by genetic mutations in ion channel genes, or acquired due to medications, electrolyte imbalances, or other medical conditions. Diagnosis is based on ECG findings and scoring systems like the Schwartz criteria. Management includes lifestyle modifications, beta-blockers, and in high-risk cases, implantable cardioverter-defibrillators (ICDs). Awareness of LQT is crucial in India, where genetic testing and specialised cardiac care are expanding. For medical students and cardiology aspirants, LQT is a high-yield topic in NEET PG and other entrance exams, as it bridges genetics, electrophysiology, and clinical management.

Example
The cardiologist advised an ECG for the young patient with recurrent fainting, suspecting LQT after hearing about the family history of sudden cardiac death.
LQT — frequently asked questions
What is the full form of LQT?
The full form of LQT is Long QT syndrome, a cardiac condition involving prolonged ventricular repolarisation visible on an ECG.
What are the symptoms of LQT syndrome in Indian patients?
Symptoms include syncope (fainting), palpitations, seizures-like episodes, and a family history of sudden cardiac death, often triggered by exercise or emotions.
How is LQT treated in India?
Treatment includes beta-blockers like propranolol, lifestyle changes (avoid strenuous activities), and ICD implantation for high-risk patients. Genetic counselling is also recommended.
