Adaptive-rate pacemakers. Comparison of sensors and clinical experience.
Many types of artificial sensors for adaptive-rate pacing have appeared but as yet there is no single sensor that properly reflects metabolic demand under all circumstances. Several other types of sensors are currently evaluated. Combinations of different sensors in a single unit are very promising. At present, however, the only completely satisfactory sensor is the normal sinus node.
