Lifestyle modification and medical treatment of long QT syndrome

Studies have shown that many manifestations can be observed for patients suffering from long QT syndrome (LQTS), as it is a common cause of syncope and mortality among younger patients, in addition to convulsions. Many management modalities for LQTS have been described in the literature including medical treatment modalities and lifestyle modification approaches. However, evidence regarding the outcomes of these approaches is continuously updating. In this study, we have reviewed findings from the current studies in the literature about the medical treatment and lifestyle modifications for patients suffering from LQTS. Furthermore, studies have shown that β-blockers are effective modalities and should be used at a maximum dose. However, the potential side events should be considered and adequately managed and patient compliance should be maintained along the course of treatment. Implantable cardioverter-defibrillator (ICD) implantation and LCSD were also discussed in the present study with their favorable indications. Additionally, lifestyle modifications were also important and have been reported with favorable events and therefore, these should be considered in such situations. However, evidence regarding some approaches as limiting competitive exercises is still conflicting, indicating the need for future investigations.
