An electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain. An EEG tracks and records brain wave patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results.
A nerve conduction velocity test (NCV) is an electrical test that is used to determine the adequacy of the conduction of the nerve impulse as it courses down a nerve. This test is used to detect signs of nerve injury.
An electrophysiology (EP) study is a test that records the electrical activity and the electrical pathways of your heart.
It can help find what’s causing your irregular heartbeat. It also helps figure out the best treatment for you.
During the EP study, your doctor will safely reproduce your heart rhythm. Then, he may give you different medicines to see which controls it best.
