1. A heart pacemaker for supplying sequences of stimulation pulses for effecting termination of a sensed tachycardia, said pacemaker comprising at least a signal detector, a controllable stimulation pulse generator for generating stimulation pulses with a controllable time interval, and a tachycardia detector, and further comprising a memory with a plurality of register means constructed for storing respective register values controlling generation of respective sequences of n stimulation pulses, said register means during pacemaker operation serving to store register values corresponding to respective sequences that are effective for the termination of a tachycardia and thereafter to supply the stored, register values during a subsequent tachycardia to control the generator to again supply the corresponding sequence, and control logic means coupled with said tachycardia detector for activation in response to a tachycardia and controlling selection of the respective register means to selectively effect the supply of the respective stored register values for the corresponding control of said generator.
