Development of a portable multipurpose recorder using a 24-hour ambulatory recorder: application to polysomnography.

摘要

With the advance of chronobiology, demands for simultaneous long-term monitoring and recording of various biosignals are increasing. To meet these demands we have developed a portable multipurpose recording system using a 24-hour ambulatory recorder. This technical achievement of less restrictive round-the-clock simultaneous recording of biosignals from not only the circulatory system, but also from the neurological and digestive systems of a subject in his/her daily life will contribute to clinical research on circadian variations of biosignals and EEG analysis during sleep.
