An implantable system stimulates a human or animal heart. The system contains a processor, a memory unit, an atrial stimulation unit, a ventricular stimulation unit, and a detection unit for detecting atrial tachycardia. The memory unit stores a computer-readable program that prompts the processor to: a) detect by the detection unit whether atrial tachycardia to be treated is present in the heart; b) when atrial tachycardia to be treated is present, carrying out a ventricular conditioning stimulation by way of the ventricular stimulation unit; and c) applying atrial antitachycardia pacing in the form of a stimulation pulse sequence of 2 to 20 pulses or a high-frequency burst having a frequency of up to 50 Hz and a duration of up to 60 seconds by way of the atrial stimulation unit as the ventricular conditioning stimulation is being carried out and/or thereafter.
