Abstract: A method of monitoring and/or diagnosing an autoregulation mechanism of blood pressure of a living being using an ECG signal includes recording the ECG signal of the living being, and the recording a pulse wave curve synchronously with the recording of the ECG signal. Heart rate intervals are determined from the ECG signal. A pulse wave transit time is determined for each heart rate interval from the pulse wave curve. A plurality of significant changes in the pulse wave transit times are determined according to a specified criterion. One respective heart rate interval correlated in time with each significant change in the pulse wave transit times is selected as an anchor point. A determined limited number of temporally successive heart rate intervals temporally before and/or after each anchor point are selected to thus generate a limited sequence of heart rate intervals for each anchor point.
