Abstract
A rate responsive pacemaker with improved response to exercise onset includes a detector for detecting a metabolic parameter indicative of the patient's metabolic demand. The metabolic demand parameter derived therefrom is analyzed either using a heart rate sensitive zero crossing detector or a derivative calculator and used to generate an optimized pacing rate.
