Cardiovascular variability e.g. heart rate, determining device, has measuring unit measuring heart regulation time signal and oxygen saturation of blood, and evaluation device transferring measured values into electrical variability signals

摘要

The device has a measuring unit measuring heart regulation time signal, blood flow and oxygen saturation of blood of human, where the measuring unit receives a photoplethysmogram. An evaluation device transfers measured values into electrical variability signals. The measuring unit measures blood pressure. Information and classifications about cardiovascular regulation characteristics are made from the heart regulation time signals.
