Electroseismogyrocardiography Units for Measuring the Human Biophysical Signals

The article is devoted to the development of an electroseismogyrocardiography unit (ESGCU) for studying human biophysical signals. Well-known technical solutions for monitoring the basic parameters of the human body functioning are presented. The authors present an ESGCU design based on a high-resolution electrocardiography unit with a USB interface and a seismogyrocardiography unit for synchronous recording and analysis of electroseismocardiosignals. Schemes of electrocardiography units with radio and USB interfaces for recording electrocardiosignals are also presented. A seismogyrocardiography unit based on micromechanical sensors for recording the chest excursion and determining the spatial orientation of a person is considered. The results of examining the ESGCU biophysical signals are presented. Methods for determining the parameters of an emergency condition and of ESGCU design with a radio interface for diagnosing the emergency are described.
