Effect of Endoscopy on St. Jude Medical Implantable Cardiac Rhythm Devices

Background

Endoscopic procedures like gastroscopy and colonoscopy should not interfere with cardiac pacemakers or implantable cardioverter defibrillators (ICDs). If electrocautery is not used, we do not anticipate any damage or reprogramming to the pacemaker or ICD nor is there a need to turn an ICD off.

If electrocautery is used during an endoscopic procedure, the electrocautery can affect the operation of pacemakers and ICDs. While all St. Jude Medical devices incorporate circuits and designs intended to prevent or minimize such effects, the high energy levels used in electrocautery can produce electromagnetic interference (EMI) that can be sensed by the implanted device. When such signals are erroneously interpreted as cardiac activity by the implanted device, inappropriate therapy delivery or inhibition of pacing may occur. A high voltage shock delivered to a patient during a procedure may disrupt delicate surgery. Please see the recommendations for electrocautery involving ICDs or pacemakers.
