Dysrhythmia is noted by an abnormal progression of the brain wave.
There are many variations of this condition, but the most common are:
Stage I dysrhythmia: a frontal displacement or lack of parietal involvement
Ipsilateral dysrhythmia: when the patient presents physical dysfunction of one side of the body, it is often associated with an abnormal shift of the P300 to that same side within the brain.
Evoked potential abnormalities: The brain generally takes 500 msec to respond fully to stimuli. Evoked potential abnormalities show dysrhythmias that may occur many times within this 500-msec time interval. The amount of times these dysrhythmias occur is contingent upon the severity of brain dysfunction. In general, there is a correlation between the severity of brain dysfunction and the number of evoked potential abnormalities evidenced on a brain map.
The BEAM interpretation incorporates elements of the dysrhythmia scale developed at the Mayo Clinic, defining a progressive disorganization of brain function. In brain mapping, we look at this condition as occurring within one to four quadrants (lobes) of the brain.
When one quadrant is involved, it is a less serious event than multiple quadrants.
