Specialized technicians administer EEGs at hospitals, doctor’s offices, and laboratories. The electrodes transfer information from your brain to a machine that measures and records the data. An electrode is a conductor through which an electric current enters or leaves. Other factors that can influence your EEG reading include:Īn EEG measures the electrical impulses in your brain by using several electrodes attached to your scalp. The person responsible for interpreting your EEG will take these movements into account.
Several types of movements can potentially cause “artifacts” on an EEG recording that mimic brain waves. Factors that could interfere with an EEG reading Some people may not be able to hyperventilate safely, such as people with a history of stroke, asthma, or sickle cell anemia. Hyperventilation is also commonly induced during an EEG to produce abnormalities. The technician performing the EEG is trained to safely manage any situation that might occur. When someone has epilepsy or another seizure disorder, there’s a small risk that the stimuli presented during the test (such as a flashing light) may cause a seizure. If an EEG does not produce any abnormalities, stimuli such as strobe lights, or rapid breathing may be added to help induce any abnormalities. If you think you may have a medical emergency, call your physician or 911 immediately.EEG is usually painless and very safe. By using this Site you agree to the following Terms and Conditions.

Thus an EEG measures the electrical avtivity of brain while the ECG measurs the activity of the heart.Refer Best An ECG may be included as part of a routine examination in patients over 40 years old. If a person is on medications that may affect the heart or if the patient is on a pacemaker, an ECG can readily determine the immediate effects of changes in activity or medication levels. If a person has chest pain or palpitations, an ECG is helpful in determining if the heart is beating normally. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker) An ECG is very useful in determining whether a person has heart disease. An electrocardiogram (ECG) is a test that records the electrical activity of the heart. The EEG may be done to confirm brain death in a comatose patient. It is also used to evaluate sleep disorders and to investigate periods of unconsciousness. EEG is used to help diagnose the presence and type of seizure disorders, to look for causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases, and metabolic disturbances that affect the brain. Certain conditions, such as seizures,can be seen by the changes in the normal pattern of the brain's electrical activity.
The computer records your brain's electrical activity on the screen or on paper as wavy lines. Special sensors electrodes are attached to your head and hooked by wires to a computer. An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain.
