Heart systolic interval measuring system - is controlled by respiration phases using sensor for measurement at given interval after each phase change

摘要

Systolic intervals, used for evaluating the heat circulation function are measured by using a sensor to detect the respiration phases. Each systolic internal measurement can be made following each change in the respiratory phase. PRef. each measurement is made at a selected time interval after the change of phase. The change-over from breather-in to breathing-out may be recorded on print-out strip. The systolic measurements may be performed digitally, with the mean value for e.g. each (1) heartbeats being used, the mean values being compared and their difference, sum or quotient used to establish the trend over a given period.
