Abstract
A method for identifying a characteristic profile of an R-wave in an EKG signal is proposed. A temporal sequence of measurement values is recorded and stored with associated time value. A number of values for identified temporal derivative and their respective time values is identified in the stored measurement values. One of the values for identified temporal derivative is selected as an exemplary value. The selection includes at least one plausibility test. A sub-sequence of the stored measurement values is selected as a characteristic profile as a function of the time value associated with the exemplary value. The combination of identifying possible values by their derivative with a plausibility test makes the method particularly robust.
