An implantable heart stimulator comprises a pulse generator (3) for delivering stimulation pulses to the heart of a patient. An IEGM means (5) registers electric signals associated with the patient's heart. A classifier means (6) classifies received electric IEGM signals according to their waveforms in at least one segment of the cardiac cycle, and a control means (4) controls the pulse generator depending on the classification of the IEGM signals. A first filtering means is provided to extract parameters related to the patient's respiration from beat-to-beat variability in the IEGM signal classification while filtering away slow classification variability extending over several cardiac cycles. The control means is adapted to receive the respiration-related parameters to control the delivery of stimulation pulses from the pulse generator depending on these parameters.
