Navigating public spaces with a pacemaker often brings questions about security checkpoints. Understanding how these devices interact can alleviate concerns and ensure a smooth experience in various environments. This article offers clarity on common interactions between pacemakers and detection technologies.
Understanding Pacemakers and Metal Detectors
A pacemaker is a small, battery-operated device implanted beneath the skin, typically in the chest, to help regulate the heart’s rhythm. It delivers low-energy electrical pulses through thin wires, known as leads, to stimulate the heart and maintain a normal beat. The device monitors the heart’s natural electrical activity and sends impulses only when needed, such as when the heart beats too slowly or irregularly.
Metal detectors, conversely, operate by emitting an electromagnetic field to identify metallic objects. A transmitting coil creates this field, and when metal enters it, eddy currents are induced in the metallic object. This interaction creates a disturbance in the original electromagnetic field, which a receiving coil detects, triggering an alarm.
Safety Guidelines for Pacemaker Wearers
Individuals with pacemakers can generally navigate environments with metal detectors safely. It is helpful to inform security personnel about the implanted device before screening. Carrying a medical device identification card provides quick verification of the pacemaker.
When encountering walk-through metal detectors, it is advisable to proceed at a normal walking pace and avoid lingering or leaning on the archway.
If a hand-held wand is used, request that the security operator avoid holding it directly over the pacemaker site for more than a few seconds. Waving the wand repeatedly over the device should also be avoided. As an alternative, a pat-down search can be requested.
Common Detection Technologies and Pacemakers
Walk-through archway metal detectors, commonly found in airports and courthouses, are safe for individuals with pacemakers. Studies indicate that normal passage through these detectors does not interfere with a pacemaker’s pacing or sensing functions. However, the metallic components of the pacemaker may activate the alarm, which is a normal occurrence.
Hand-held wands, used for more targeted screening, are safe for brief exposure. Security personnel are trained to conduct scans quickly over the device area.
Retail anti-theft systems, also known as Electronic Article Surveillance (EAS) gates, use electromagnetic fields to detect security tags. Passing through these systems at a normal pace is safe. However, prolonged exposure, such as lingering or leaning near these gates, should be avoided.
