Mathematical functions such as recursive autoregression models which include parameters are used for defining the heart signal and any signals disturbing the heart signal, such as polarization signals. By registering, during a predetermined time interval, the electrode signal for determining the parameters for one or more different mathematical functions, the parameters can be used on their own or in combination to determine the activity of the heart, i.e., whether the registered electrode signal corresponds to a stimulated, spontaneous or absence of heart activity. |
