MEDICAL AND DENTAL PROCEDURES Electromagnetic Compatibility Guide

For Implantable Cardiac Devices

Medical and Dental Procedures

Many medical procedures will not affect your heart device; however, certain medical procedures can result in serious injury, damage to your heart device, or device malfunction. Before undergoing any medical procedure, it is recommended that you advise your treating doctor or dentist that you have an implanted heart device and consult with your heart doctor to evaluate any possible associated risk.


If the item is used as intended and in good working condition, there is no known risk:

  • Acupuncture – no electrical stimulus
  • Acupuncture DC – direct current
  • Bone Density Test (x-ray)
  • Bone Density Ultrasound – on heel or hand
  • Bone Growth Stimulator – direct current
  • Capsule Endoscopy
  • Colonoscopy – diagnostic only
  • Dental Apex Locator (root locator)
  • Dental Drills
  • Dental Pulp Tester
  • Dental Ultrasonic Scalers/Cleaners
  • Dental X-Ray
  • Diagnostic Ultrasound (sonogram)
  • Diagnostic x-rays (fluoroscopy)
  • Digital Infrared Thermal Imaging (DITI)
  • Echocardiogram
  • Enhanced External Counter Pulsation Therapy (EECP)
  • Electrocardiogram (ECG/EKG)
  • Electroencephalography-EEG
  • Electronystagmography (audiology – ENG)
  • Hearing Aid (in or behind ear)
  • Heart Rate Monitor
