To the Editor:-Recently, Broka et al. [1] described the use of transesophageal atrial pacing as a trigger for an intraaortic balloon pump (IABP). I have had difficulty in doing so with the IABPs I have available. In some situations, the IABP console did not recognize the atrial stimulus, and sometimes recognized it as the ventricular complex (Datascope Systems 90 and 95 respectively, Datascope, Paramus, NJ). In the latter situation, appropriate timing could be achieved by significantly delaying inflation and deflation when timing off of the transesophageal atrial pacing stimulus. In our cases, fortunately, we were able to time the IABP off the pressure waveform. It would be of interest to know which IABP they used.
