DC cardioversion (DCCV)
DC cardioversion (DCCV) is used to treat irregular heart rhythms
(commonly atrial fibrillation). The procedure involves a general
anaesthetic and placement of electrodes on the chest. An electrical
impulse is passed across the electrodes to return the heart rhythm
to normal.
