Long QT syndrome - Diagnosis For other cases of acquired long QT syndrome, treating the underlying condition is necessary. For other cases of acquired long QT syndrome, treating the underlying condition is necessary. In LQTS, the lower chambers of the heart (ventricles) take too long to contract and release. QT Interval Core tip: Long QT syndrome is a cardiac conduction disorder characterized by prolongation and increased dispersion of ventricular repolarization, manifested by lengthening of the QT interval on the surface electrocardiography. Long QT Syndrome (LQTS) Explaining the problem. It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. Congenital long QT syndrome (LQTS) is an inherited disease, it has several forms, and is caused by mutations in the genes encoding specific ion-channel subunits or regulatory proteins. More than 17 genes have been linked to long QT syndrome so far, and researchers have identified hundreds of mutations within these genes. Because feeling physical pain is vital for survival, CIP is an extremely … Long QT syndrome (LQTS) is a cardiac electrophysiologic disorder, characterized by QT prolongation and T-wave abnormalities on the EKG that are associated with tachyarrhythmias, typically the ventricular tachycardia torsade de pointes (TdP). It is caused by an abnormality in the gene code for the ion channels. For other cases of acquired long QT syndrome, treating the underlying condition is necessary. Congenital Long QT syndrome is diagnosed on the basis of electrocardiographic (EKG) findings, clinical findings such as congenital deafness or unexplained fainting, and family history of long QT syndrome or sudden cardiac death. The hereditary long QT syndromes (LQTSs) (Graphical Abstract) are an important cause of sudden cardiac death in the young. Among untreated patients who have experienced one episode of syncope, 20% die within 1 year. Medications. Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more extraordinarily rare conditions in which a person cannot feel (and has never felt) physical pain. Treatment varies but may include magnesium or other fluids given by IV to correct electrolyte imbalances. Short QT syndrome appears to have an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell is sufficient to cause the disorder.

Long QT syndrome (LQTS) is a condition in which repolarization of the heart after a heartbeat is affected. Treatment options include beta-blockers, pacing to maintain faster heart rates (which shortens the QT interval), and the ICD, alone or in combinations.
