This is a serious cardiac disorder which maybe congenital or acquired due to intake of certain medications.It is characterized by the prolongation of QT interval on ECG, in an otherwise young healthy individual with no prior complaints. Although sometimes the patient may give a history of fainting spells and chest pain especially while exercising, swimming or during an emotional event. Since it can be congenital it is imperative to seek evidence of sudden cardiac death in family members especially at a young age. Long QT syndrome can also present with seizures hence it is commonly misdiagnosed and treated as epilepsy.Treatment involves medication and sometimes patients may require a pacemaker.Certain lifestyle changes such as avoiding causative drugs, strenuous exercises, swimming, contact sports, emotional stress are advocated.
