PHYSIOLOGICAL IMPLANTABLE PACEMAKER WHICH STIMULATION RATE IS CONTROLLED BY THE PATIENT'S RESPIRATORY RATE.

Abstract

Abstract This invention concerns an implantable cardiac pacemaker in which the stimulation rate is determined through a suitable programmable algorythm by the patient's ventilation rate which is taken by measuring the impedance variations throughout a distance within the human body; preferably a distance within the thoracic region that goes between the pacemaker box and the lead which is placed subcutaneously. Peculiarities of the pacemaker concerned are the ability of detecting variations, even rapid ones, of the corporeal impedance and of discriminating substantial width variations attributable in all probability to a respiratory act, furthermore as well as a limited drain of electrical energy.
