Electroencephalograms (Eeg)

An electroencephalogram (EEG) is a recording of electrical current potentials spontaneously from nerve cells in the brain onto the skull. Variations in wave characteristics correlate with neurological conditions and are used to diagnose conditions. EEGs can be transmitted by telephone in which electrical brain activity is recorded and transmitted to an off-site center for interpretation and report or by radio or cable in the diagnosis of complex seizure variants which require inpatient monitoring, but do not require the patient to be in bed. EEGs can be recorded by 24-hour ambulatory cassette. Twenty-four-hour ambulatory cassette-recorded EEGs offer the ability to record the EEG on a long-term, outpatient basis. Electrodes for at least 4 recording channels are secured on the patient. The cassette recorder is attached to the patient’s waist or on a shoulder harness. Recorded electrical activity is analyzed by playback through an audio amplifier system and video monitor. Electroencephalographic video monitoring is the simultaneous recording of the EEG and video monitoring of patient behavior. This allows for the correlation of ictal and interictal electrical events with demonstrated or recorded seizure symptomology. This type of monitoring allows the patient’s face or entire body to be displayed on a video screen. <a id="
