Abstract

The invention relates to a method and device for recording and presentation of physiological parameters, which can include both blood pressure and heart pulse. Information about the heart pulse is derived from a recorded blood pressure signal, whereby the need for e.g. an external ECG measurement device is eliminated. It is likewise a part of the invention that a blood pressure measurement is used for the derivation of data such as Heart Rate Variability (HRV) and/or baroreflex sensitivity (BRS) values
