title: Use of rapid atrial pacing to induce 2:1 atrioventricular block with marked improvement in hemodynamics.
abstract: Rapid atrial pacing by means of temporary atrial pacing wires was used to effect a regular sinus rhythm in a patient with 2:1 atrioventricular block and frequent premature atrial contractions. The change in rhythm allowed effective intra-aortic balloon counterpulsation and markedly improved the hemodynamic situation.
