Prior to SCUBA diving or starting an HBOT program, the patient’s attending cardiologist or electrophysiologist
should be consulted t o fully understand the potential consequences relative to the patient’s specifichealth
condition. A Dive Medicine Specialist may also be consulted prior to SCUBA diving.
More frequent device follow-up may be warranted in conjunction with HBOT or SCUBA diving. Evaluate pulse
generator operation following high pressure exposure ("Post-Therapy Pulse Generator Follow Up" on page 18).
The extent, timing, and frequency of this evaluation relative to the high pressure exposure are dependent upon
current patient health, and should be determined by the attending cardiologist or electrophysiologist.
If you have additional questions, or would like more detail regarding the test protocol or test results specificto
HBOT or SCUBA diving, contact Boston Scientific using the information on the back cover.
