A dual chamber pacemaker system is disclosed with means for operating in one or another of alternate rate adaptive modes. The pacemaker incorporates an atrial synchronous mode, wherein, pacing rate is determined as a function of sensed atrial signals. It also incorporates a T.sub.x mode, wherein pacing rate is controlled by a sensed QT interval, and an extra sensor mode, wherein pacing rate is controlled as a function of at least one sensed body parameter. The pacemaker comprises means for automatically testing the applicability or appropriateness of the mode currently in use, and for automatically selecting the appropriate rate control mode.
