WebThe present invention relates to an implantable medical device for stimulating a human or animal heart, comprising a processor, a memory unit, a first stimulation unit configured to stimulate an atrium of a human or animal heart, a second stimulation unit configured to stimulate a ventricle of the same heart, a first detection unit configured to detect an … WebThe first is that the amplitude of the pacemaker's motion, unlike its period, is markedly temperature-dependent. The second is that latitudinal variation in pacemaker amplitude (higher in the north) is responsible for two very different sets of observations on Drosophila circadian systems at successively higher latitudes. marybeth horton
