title: [Disorders of glottic rhythm].
abstract: Pitch perturbations are well known to be significantly less in normal voices than in pathological voices. In the present work, it is shown that, in 48 pathological voices from a sample of 73, specific dysrhythmic patterns, usually intermittent, may be demonstrated by means of electroglottography: alternating rhythms, geminate rhythms, volleys, brady- and tachydysrhythmia's. They are a result of physical perturbations of the laryngeal oscillator, induced by specific pathological conditions. Their different occurrence in the various categories of voice disorders may contribute to a more precise etiological diagnosis.
