title: [The 4 c/sec rhythm (case report and differential diagnosis) (author's transl)].
abstract: Report on a female patient with a 3 c/sec rhythm. The 3 c/sec rhythm is a special case of the 4 +/- 1 c/sec rhythm. The characteristics of this variant are reviewed in tabulated form. The differential diagnosis has to take into consideration other slow posterior rhythms like the so-called delta-parenrhythmia and delta-parenrhythmia, abortive forms of spike and wave complexes and the abnormal delta-rhythms and sinusoidal delta-rhythms in the infantile EEG.
