Abstract
An apparatus for determining an arrhythmia of a living heart comprises a signal evaluation device receiving a signal representing a present electric activity of the heart, and determining a frequency spectrum of the signal. The apparatus further comprises a pulse generator generating a sequence of electric pulses to be applied to the heart at a pulse repetition frequency that depends on the frequency spectrum and decreases by at least 20% over the sequence.

An apparatus for terminating an arrhythmia of a living heart, the apparatus comprising:
- a signal evaluation device configured for receiving a signal representing a present electric activity of the living heart, and for determining a frequency spectrum of the signal;
- and
- a pulse generator configured for generating a sequence of electric pulses to be applied to the living heart at a pulse repetition frequency that depends of the frequency spectrum in such a way that the pulse repetition frequency of the electric pulses decreases by at least 20% over the sequence.
An apparatus for terminating an arrhythmia of a living heart, the apparatus comprising:
- a signal evaluation device comprising stored evaluation instructions and, when executing the stored evaluation instructions, being configured for receiving a signal representing a present activity of the living heart, and for determining a frequency spectrum of the signal;
- and
- a pulse generator comprising stored generation instructions and, when executing the stored generation instructions, being configured for generating a sequency of electric pulses to be applied to the living heart at a variable pulse repetition frequency of the electric pulses decreases by at least 20% over the sequency.
