Can patients with pacemakers and ICDs safely pass through airport metal detectors?

Yes, patients with pacemakers and implantable cardioverter-defibrillators (ICDs) can generally pass through airport metal detectors. However, it is recommended to inform security personnel about your implanted device and present your device identification card. Although the risk of damage is low, your device may trigger the metal detector alarm [5].

Understanding Pacemakers and ICDs

A pacemaker is a small, battery-operated device that sends electrical signals to your heart to help it beat at a correct rhythm, used to correct abnormal heart rhythms [1]. An implantable cardioverter-defibrillator (ICD) is a device that monitors heart rhythms, and if it detects dangerous rhythms, it sends a quick electrical shock to restore the heart's rhythm to normal [1]. Many modern ICD devices can also function as a pacemaker [2]. These devices are designed to withstand common interference, but it is important to take certain precautions.

Passing Through Security Checkpoints

When passing through airport security checkpoints, it is recommended to follow these guidelines to ensure your safety and the safety of your device:

• Present your device identification card: Always carry your pacemaker or ICD identification card. This card contains information about your device type, the date of implantation, and your doctor's contact information [5]. Show it to airport security personnel.
• Request an alternative screening: Although body scanners used at airports appear to be safe for people with pacemakers, you can show your ID card and request a separate screening if you are concerned [5].
• Avoid prolonged contact: If you choose to walk through the metal detector, do so quickly. Avoid stopping or leaning against the equipment.

Potential Interference with Electronic Devices

In addition to metal detectors, holders of pacemakers and ICDs should avoid close or prolonged contact with electrical devices or equipment that contain strong magnetic fields. These devices can disrupt your device's electrical signals and prevent it from working properly. To stay safe, keep your device at least 6 inches (15 cm) away from such equipment, or use them only briefly when necessary [5]. For example, when using mobile phones, use speaker mode or hold the phone to the ear opposite the side of your body where your device is located. Avoid placing the mobile phone in your shirt pocket [5].

When to Seek Medical Help

If you experience any unusual symptoms after passing through a security checkpoint or being exposed to an electronic device, such as dizziness, fainting, or shortness of breath, you should immediately move away from the source of interference and contact your doctor right away [5]. These symptoms may indicate that your device is not functioning properly and requires urgent medical evaluation.
