Ion channelopathies

Ion Channelopathies

Congenital ion channel diseases (long QT or short QT syndromes, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia) are a group of rare cardiac arrhythmia syndromes caused by genetic changes in certain ion channels in the heart muscle. This affects the electrical functioning of the heart and may lead to malignant arrhythmias, syncope and cardiac arrest. Athletes with a congenital ion channel disease should not participate in competitive sport.
