摘要
For terminating a high frequency arrhythmic electric state of a biological tissue an electric signal representative of the present electric state of the biological tissue is obtained. From the electric signal a dominant frequency of the present electric state is determined, and from the dominant frequency it is determined whether the present electric state of the biological tissue is a high frequency arrhythmic electric state. Further, a dominance level indicative of how dominant the dominant frequency is in the high frequency arrhythmic electric state is determined from the electric signal. Depending on the at least one dominant frequency, at least one series of electric pulses at intervals is generated. The electric pulses are applied to the biological tissue starting at a point in time at which the dominance level exceeds a predefined threshold value for the biological tissue being in a determined high frequency arrhythmic electric state.
