Abstract: A system for the monitoring of a patient's physiological condition, including a measuring device for measuring the mechanical activity of a patient's body, including a module for detecting mechanical vibrations and transmitting same to a sensing element for converting the mechanical movements into electric signals. A device for transmitting the electric signals for processing the electric signals and separating from them cardiac, respiration and body movement signals. A device for measuring the pulse wave propagation rate. A device for determining the characteristics and derived parameters of cardiac and respiratory cycles, as well as for storing and displaying the data. A comparator for comparing parameters of the data with predetermined parameters and a device for actuating an alarm signal when signals of the data exceed a preset range.
