Hydroelectric Dam Tour
Do not attend tour: The policy of the Hoover Dam does not recommend that
individuals with an ICD go on tour within the dam because of the 50 /60 Hz magnetic
field present. Other Hydroelectric dams may have policies for ICD individuals that
differ from those of the Hoover Dam. Because of the uncertainty of the magnetic
environment within other Hydroelectric plants, we cannot predict the intensity of the
magnetic field within any specific dam. There is the potential for Pacemaker or ICD
interaction. Consult physician for level of risk that interaction with the device may
present. Tours of non hydroelectric dams would pose a low risk of affecting the
Pacemaker or ICD. Visiting outside any hydroelectric dam reduces the risk of EMI
interaction.
Hoover Dam

Scuba Diving
Use precautions: Consult with heart doctor. Prior to SCUBA diving the patient’s heart
doctor should be consulted to assess the potential consequences relative to the
patient’s specific health condition. It is possible that your physician may suggest that
you limit certain activities, such as scuba diving, to a level that is more restrictive
based on medical concerns rather than the single factor of pressure tolerance of your
pacemaker/ICD. Because of many factors associated with scuba diving, specific depth
limitations cannot be provided. Some of the factors include the possibilities of blows
to the area of the device during the time the device is under pressure stress, the
number of pressure cycles the device is exposed to over the implant time of the
device, and the activity or exertional level of the individual during the dives. Our
device pressure testing is conducted for compatibility with hyperbaric chamber
therapy. We can share with you that a pressure of two and one-half atmospheres
absolute is the maximum pressure recommended for hyperbaric chamber therapy.

Use precautions: Maintain at least a 6 inch (15 cm) separation between the magnet
associated with the badge and the implanted device.
Badge Reader (Security)
Use precautions: Maintain at least a 6 inch (15 cm) separation from wall unit (reader)
and the implanted device. Radio Frequency Identification (RFID) is a wireless
technology used to identify RFID tags mounted on objects or carried by (or imbedded
in) people or animals. Data stored in the RFID tag is read by wireless devices, called
RFID readers. The RFID reader contains one or more RF antennas that emit RF signals
within a specified range. When an RFID tag enters the reader's RF signal field,
information stored in the tag is captured by the reader. Each RFID tag relies on the
reader to transmit information contained in the tag.
RFID readers may be a potential source of EMI and could have temporary effects on
implanted cardiac devices. Because the presence of RFID systems may not always be
apparent in public and occupational settings, patients who feel symptomatic (e.g.,
light-headed, fast heart rate) should move away from nearby electrical equipment (or
the identifiable RFID system), and call their physician to report the episode.
