EEG spikes

EEG sharp wave is a triangular wave with a time limit of 80 ~ 300MS, the shape is fast and straight rise and slowly decline, the amplitude can reach more than 200μV, is also a pathological wave, is a cortical stimulation phenomenon, more common in epilepsy. Don't be nervous when checking, put the receiving electrode on the scalp, not energized; relax the whole body muscle to avoid interference with myoelectricity; blink, close your eyes or breathe as required by your doctor. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Tips: Wash your hair, don't lick oil; eat enough to prevent hypoglycemia from affecting the results. All kinds of drugs should be stopped 3 days before the test. Those who can not stop the drug should explain the name, dosage and usage of the drug for the doctor's reference. Normal value The frequency of normal human EEG is almost entirely composed of α wave and β wave. The amplitude and frequency of the waveform are uniformly symmetrical on both sides, the frequency is constant, and the amplitude can be different by 30 on both sides. Clinical significance Abnormal result A triangular wave with a time limit of 80 to 300 MS and a shape that rises slowly and slowly decreases, and the amplitude can reach 200 μV or more. It is also a pathological wave and is a cortical stimulation phenomenon, which is more common in epilepsy. Need to check the crowd: people with epilepsy. Precautions Contraindications before the examination: wash the hair, do not lick the oil; full meal, to prevent hypoglycemia affect the results; 3 days before the examination to stop all kinds of drugs, can not stop the drug to explain the name, dosage and usage, so that the doctor can refer to. Requirements for inspection: Do not be nervous when checking, place the receiving electrode on the scalp, not energized; relax the whole body muscle to avoid interference with myoelectricity; blink, close your eyes or breathe as required by your doctor. Inspection process Sitting or lying, closing your eyes, quiet, relaxing, not moving, getting ready, the doctor takes the patient quietly and then checks the EEG. Not suitable for the crowd Inappropriate crowd: no Adverse reactions and risks Nothing.
