Abstract
An implantable stimulating device for electrical stimulation of a heart has a stimulus generator which generates electrical stimuli and at least one lead for delivering the stimuli from the generator to the heart. A measurement unit detects spontaneous intervals between successive intrinsic heartbeats, and forms an average of at least five of these spontaneous intervals. A variation with respect to this average for later spontaneous intervals is then identified, and this variation is then used to control a pacing parameter of the stimulus generator.
