WebThe congenital long QT interval syndromes result from genetic disorders of cardiac ion channel function or regulation (channelopathies) that prolong ventricular myocyte action potential duration as reflected by prolongation of the rate-corrected QT interval on the ECG (QTc, typically calculated using Bazett's formula). WebNeurological sodium channelopathies are childhood-onset disorders caused by mutations in genes that encode the α subunits of voltage-gated sodium channels or their interacting β subunits. All the voltage-gated sodium channel isoforms expressed in either the muscle or the brain have a crucial role in tissue excitability—their primary ...
