LCSD

Some more on treatment options:
Arthur Moss performed the first left cardiac sympathetic denervation (LCSD) in a patient with the long QT syndrome in 1971. As opposed to beta blockers which simply block the ability of adrenaline to bond to beta receptors in the heart, LCSD removes the ganglia which supply adrenaline to the heart. In the same way beta blockers limit the heart’s reaction to adrenaline, LCSD reduces the QTc by minimising the QT stunning and stretching.
LCSD surgery is usually only recommended for people with long QT syndrome and persistent rhythm problems who can’t take or tolerate beta blockers. It doesn’t cure long QT syndrome, but it does help reduce the risk of sudden death. LCSD helps bridge the gap between beta blockers and implanting an ICD which should be reserved for the highest risk patients.
