New and combined sensors for adaptive-rate pacing.
Clin Cardiol
March 1993
Department of Cardiological Sciences, St. George's Hospital Medical School, London, England.
A new potential indication for cardiac pacing is chronotropic incompetence, that is, an inadequate cardiac rate response to exercise and other metabolic demands. Many patients who have been paced for indications such as complete heart block or sick sinus syndrome also have chronotropic incompetence. Such patients are not adequately treated when fitted with a constant rate pacemaker.

The atrial synchronous pacemakers are superior to the ventricular inhibited fixed rate pacing mode. Alternative methods of sensing physiological demands with single chamber ventricular pacing that produce a physiological rate response to exercise are described.
