Sinus bradycardia during anesthesia is often acute in onset, may produce hypotension, and may lead to more serious dysrhythmias. The response of bradycardia to pharmacoligical interventions is unpredictable, and therefore cardiac pacing provides a more precise and effective treatment. We report our experience with 37 surgical patients with intact AV conduction who were successfully treated by transesophageal atrial pacing for hemodynamically significant bradycardias.
