Waveforms and Artifacts

Show Summary Details

Preview

Artifacts can alter all of the variables used to describe the continuous and discrete waveforms recorded in clinical neurophysiology. Changes in amplitude, frequency, and distribution of waveforms occur in continuous waveforms. Frequency change may include the addition of new, abnormal frequencies, the loss of normal frequencies, and either an increase or a decrease in amplitude. Discrete events themselves may be abnormal. The configuration, distribution, size, and pattern of normally occurring discrete events may be changed by disease.
