A new symbolic language is presented that can be used to diagram pacemaker/heart inleractions. The language symbolically indicates “normally” conducted and ecfopic events; pacemaker stimuli; pacemuker capture of the chamber; triggered pacemaker stimuli by “normal” or eclopic events: as well as such anomalous pacemcker/heart interactions as failure to sense; “crosstalk” between electrodes; and “normal,” eclopic. of paced events in one chamber sensed by the electrode in the other chamber. In addition, symbols are provided to represent antegrade and retrograde accessory pathway conduction, and electronic and physiological refractory intervals, A common baseline is used to separate symbols for atrial activity. above the baseline, from those for ventricular activity, below the baseline. Parallel baselines are used to plot refractory intervals. Thus, even complex dual‐chamber pacemaker operating modes can be represented with intrinsic and stimulated cardiac response to pacemaker operation. The language can be sketched out informally for description of general concepts or drafted on millimeter grid paper to make precise timing notations. It is especially useful for interdisciplinary communication of ideas about complex pacemaker/heart interactions. (PACE, Vol. 5. September‐October, 1982)
