[Polygraphic registration of spontaneous syncope].

A 29 year-old female patient suffered from a syncopal attack in the early morning hours. During polygraphic registration (ECG, EEG, pulse, breathing, blood pressure) on a tilt table she developed another spontaneous orthostatic syncopal attack, which was triggered off by a lengthy period of standing and was preceded by a drop in the recorded blood pressure. She was asystolic over 21 sec., the EEG did not show any bioelectric activity (with standard attenuation) over 22 sec. Within a short time she recovered fully from the clinical, as well as from the polygraphic point of view. The syncopal attack in this patient is discussed as being of the vagocardial type in connection with vagotonia. The original polygraphic data of the relevant period are presented.
