Abstract

For terminating a high frequency arrhythmic electric state of a heart an electric signal representative of the present electric state of the heart 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 heart is a high frequency arrhythmic electric state displaying at least one rotating wave. 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 heart starting at a point in time at which the dominance level exceeds a predefined threshold value for the heart being in a determined high frequency arrhythmic electric state.
