Prism‐CL R is a new single chamber unipolar pace, bipolar or unipolar sense, rate responsive pacemaker that utilizes a closed‐loop system based on the analysis of the evoked potential for rate adjustment It also has an automatic output regulation feature for capture verification and threshold search. Five patients in whom this pace maker was implanted exhibited an appropriate rate increase with exercise and psychological stress. Automatic output regulation functioned appropriately in three of five patients. Preliminary data suggest that Prism‐Cl R is an elective pacemaker for patients who may benefit from rate responsive pacing. The automatic output regulation recognition algorithm may need modification in some patients.
