title: [Ion channel diseases in children].
abstract: Ion channel diseases are responsible for the occurrence of supraventricular bradycardia and tachycardia, ventricular tachycardia, syncope and sudden death. In the present paper the specific considerations for diagnostic pathways and therapeutic decision making will be focused on for the largest clinical entities, such as the long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia and Andersen-Tawil syndrome. All diseases are characterized by a specific pathognomic electrocardiographic (ECG) alteration. For most of the diseases a variety of mutations have been identified that code for different ion channel proteins. All have a high potential of arrhythmogenicity in common. It is important to know that the ECG alterations are often only transient, which makes repetitive recordings and sometimes provocation maneuvers necessary. The time of onset of disease varies so that the initiation of diagnostics starts at different ages. Therapy often remains an individual choice and is influenced by a number of factors, such as a family history of sudden death.
