Medical procedures that may require your doctors to take some
precautions include the following:
• Mammograms, CT scans, and high-intensity fluoroscopy
• Electrosurgery and RF or microwave ablation
• External defibrillation and cardioversion
• Hyperbaric therapy (including hyperbaric oxygen therapy, or HBOT)
• Lithotripsy
• Radiation therapy and radiotherapy
• Transcutaneous electrical nerve stimulators (TENS), including
neuromuscular electrical stimulation. Because of the possible effects
on cardiac monitor data collection, discuss the use of any TENS
equipment with your heart doctor.
• Transurethral needle ablation (Medtronic TUNA therapy)
• MRI (magnetic resonance imaging) scans, which is a type of medical
imaging that uses magnetic fields to create an internal view of the
body. If your heart doctor decides you can have an MRI scan, you
may feel your cardiac monitor being pulled as a result of the
magnetic field when moving in and out of the magnetic resonance
