KnowraLong QT syndromeLinked fromLinked fromThe 14 pages that link to Long QT syndrome, each with the reason it gives.All 14Broader topic 6Related 5Compared with 3Ion channelRelated: Variants in cardiac ion-channel genes can delay repolarization and prolong the QT interval.Cardiac arrestRelated: It can provoke ventricular arrhythmias and arrest, particularly in otherwise young people.Ventricular fibrillationRelated: It can provoke torsades de pointes, which may degenerate into ventricular fibrillation.Excitation-contraction couplingRelated: Cardiac calcium cycling and contraction are coordinated with the electrical action potential.Torsades de pointesRelated: The prolonged repolarization underlying torsades may result from inherited or acquired long QT syndrome.
