1. A pacemaker system comprising an implantable dual chamber pacemaker having means for sensing atrial and ventricular events and means for timing atrial and ventricular pacemaker operation, and external apparatus for storing data and displaying data, characterized bysaid pacemaker having output means for cyclically outputting event and pacemaker timing data representative of a prior pacemaker interval;

  • said external apparatus having means for receiving and storing said outputted data in storage; and

    graphic constructing means for constructing from said stored data a dual channel graphic output representative of both atrial and ventricular pacemaker timing and events for a plurality of pacemaker cycles, said graphic constructing means further comprising linear print means for printing linear symbols respectively representative of different sensing conditions, said linear symbols having lengths representative of the time durations of said sensing conditions.
