WebBrugada syndrome is a genetic disorder that can cause a dangerous irregular heartbeat, especially during sleep or at rest. Once diagnosed, there are important changes to lifestyle and medical management that can greatly reduce the risk of serious arrhythmias. Rarely, implantable defibrillators can help reduce the risk of sudden death. Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. There are more than 400 genes that encode ion channels, f…
