We report two patients with inferior myocardial infarction, complicated by bradyarrhythmia, hypotension, and clinical evidence of right ventricular infarction. Conventional therapy of volume expansion and inotropic support was insufficient to maintain an adequate blood pressure. ⋯ We recommend consideration of these pacing modes in patients with inferior infarction with evidence of right ventricular infarction, bradyarrhythmia, and cardiogenic shock. The likely mechanism of improvement is by restoration of atrial transport with consequent improvement in ventricular function.
