The most commonly used utilized devices monitor and pace both the right atria and right ventricle. These are known as dual-chamber pacemakers; they are very susceptible to magnetic fields and forms of electromagnetic radiation, and earlier versions are contraindicated in use through magnetometers and are sensitive in electromagnetic fields of lower wavelengths.

Patients should avoid sources of magnetic and electromagnetic radiation to avoid possible underdetection, inappropriate sensing and/or therapy delivery, tissue damage, induction of an arrhythmia, device electrical reset or device damage.3 IMPLANTABLE CARDIAC DEFIBRILLATORS Implantable cardiac defibrillators (ICDs) are similar to pacemakers (see Figures 5.2 and 5.3)

Patients should avoid sources of magnetic and electromagnetic radiation to avoid possible underdetection, inappropriate sensing and/or therapy delivery, tissue damage, induction of an arrhythmia, device electrical reset or device damage. Do not place transthoracic defibrillation paddles directly over the device.5 SPINAL CORD NEUROSTIMULATOR A spinal cord stimulator (Figure 5.4)

may damage a neuro stimulator, and the electrical pulses from the neurostimulator may result in an inappropri ate response of the cardiac device.7 TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION Transcutaneous electrical nerve stimulation, also known as TENS, involves the use of small amounts of electrical currents applied to the skin for the purpose of transcutaneously stimulating the nerves to reduce chronic and acute pain (see Figure 5.5)

IMPLANTABLE INSULIN PUMPS Implantable insulin pumps deliver into the body precise and accurate levels of rapidly acting insulin to maintain the blood glucose within the normal ideal range in patients with diabetes mellitus. Newer approved technology also offers the opportunity for the patient's blood glucose level to be constantly monitored.

Patients receiving intrathecal baclofen therapy are at higher risk for adverse events, as baclofen withdrawal can lead to a life threatening condition if not treated promptly and effectively. Confirm pump status before and after MRI.

11 Additionally TSA makes the following statements related to internal and external medical devices in how the traveler can inform a TSA officer and how the screening will be conducted for: • External devices. Inform the TSA officer if you have a bone growth stimulator, spinal stimulator, neuro stimulator, port, feeding tube, insulin pump, ostomy or other medical device attached to your body and where it is located before the screening process begins.

Travelers may weigh the advice of their physicians and the device manufacturers against the absence of evidence of any deviation or effect from normal operation of preemptive medical devices when being scanned with millimeter wave AIT. Finding 5.4: Travelers with implanted medical electronic devices may wish to carry with them a proper medical identification card or a TSA notification card describing their device and to keep up to date with the latest physician and manufacturer recommendations as well as guidelines from the TSA.
