Efficacy of transesophageal and transgastric cardiac pacing in the dog.

Objectives: Determine if temporary artificial cardiac pacing can be accomplished from transesophageal or transgastric pacing sites.

Animals, Materials And Methods: Nine purpose bred Beagle dogs had a multipolar electrophysiology pacing catheter inserted transnasally and advanced into the distal esophagus or stomach under general anesthesia. Artificial atrial pacing was attempted using a bipolar configuration from the distal esophagus with the dogs in left lateral recumbency.
