Which statement is a restriction for patients with implantable devices?

• A. Iontophoresis in higher outputs
• B. Wearing magnetic jewelry around the device
• C. Regular elevation of the device above heart level
• D. None of the above

Answer: (A)

When a patient has an implanted electronic device, external electrical energy can interfere with how that device senses the heart and delivers therapy. Iontophoresis uses direct current to drive medication through the skin, and at higher outputs the electrical field it creates can couple with the device’s circuitry. This can lead to inappropriate sensing or pacing changes, and in some cases heating near the leads. Because of these risks, high-output iontophoresis is restricted for people with implantable devices. Wearing magnetic jewelry around the device and regularly elevating the device above heart level aren’t universal, all-encompassing restrictions for rehab, since the degree of risk depends on the specific device and situation. The primary concern with implantable devices in rehab modalities is the potential interference from electrical currents, which is why the high-output iontophoresis clause stands as the best answer.
