title: [Activitrax--a pacemaker with a regulated rhythm rate].
abstract: In 10 patients: 7--with the complete atrioventricular block and 3 with the sick sinus syndrome the rate responsive activity sensing pacemaker--Activitrax was implanted. Significant increase of rheographically measured cardiac output in a course of rate responsive pacing in comparison with on demand constant frequency rate stimulation was stated during treadmill exercise tests performed 6 and 12 weeks after a pulse generator implantation.
