Objective: To determine effects of catheter shape, interelectrode spacing (IS), and electrode size (ES) on pacing threshold (PT), extraneous muscular stimulation (EMS), and zone of capture (ZOC) for dogs undergoing transesophageal atrial pacing (TAP).
Animals: 10 purpose-bred dogs without cardiac conduction disturbances.
Procedures: 7 configurations for TAP catheters were tested in each dog to evaluate effects of catheter shape (curved or straight), IS (5, 15, and 25 mm), and ES (2, 4, and 6 mm).
Objective: To determine the impact of stimulus pulse width (PW) on pacing threshold (PT), zone of capture (ZOC) and extraneous muscular stimulation (EMS).
Study Design: Experimental trial in client-owned dogs.
Animals: Seventeen dogs, median weight 16.
Pericardial defects are rare in both people and dogs. They may be congenital or acquired in origin, and partial or total in extent. Commonly, pericardial defects are incidental findings at autopsy; however, diagnostic methods such as thoracic radiography and echocardiography can be useful in the ante mortem diagnosis of pericardial defects.

Study Design: Prospective clinical study.
Animals: Fourteen client owned healthy dogs with a median weight of 15.
Objective: Compare the efficacy of two cardiac pacing catheters for transesophageal atrial pacing (TAP).
Animals: Ten healthy dogs.
Methods: Transesophageal atrial pacing was attempted in left lateral recumbency under general anesthesia.
