Interference Between Pacemaker and Video Capsule Endoscopy

The wireless capsule video endoscopy is useful in patients with occult blood loss, but is contraindicated in patients with cardiac pacemaker (PM). No case of interference has been published. We report the case of a patient with a PM implanted in the abdominal wall. After capsule ingestion, cardiac monitoring showed no modification of the PM compartment (VOO, unipolar mode) but the capsule recording reveal more than 3 hours of loss of image. The wireless capsule endoscopy is safe in patients with PMs in VOO mode. Nevertheless important interference was noted in the recording when the capsule was near the PM.
