More Information
Summary:The invention relates to a processor configured to determine a dicrotic notch position of a pressure pulse by determining at least one of a notch determination intersection position, a notch determination maximum position and a notch determination function position. The notch determination intersection position is a position at which a shifted tangent to the pressure pulse intersects with the pressure pulse. The notch determination maximum position is a position at which a derivative function of the pressure pulse has a maximum. The notch determination function position is determined by applying a position determination function to a characteristic of the pressure pulse. This allows for a very accurate determination of the diagnostically relevant dicrotic notch position.
