Pacemakers at risk from store security, doctors warn

PEOPLE with pacemakers should not linger too long in shops because antitheft devices can disrupt the devices, experts have warned.

Many patients are unaware that electronic anti-theft systems can pose a threat to people using cardiac implants, they said.

Prolonged exposure to the in-store devices can cause pacemakers to drop beats and cause implantable defibrillators to deliver inappropriate shocks, experts told the Cardiostim EHRA Europace 2016 conference.

Some of the anti-theft devices are hidden under floors, in walls and in doors, while traditional pedestal systems in doorways are often covered by advertising.

A new study, presented by Prof Robert Stevenson, senior scientist at Greatbatch Medical in Santa Clarita, California, examined pacemakers against an array of anti-theft devices, also known as electronic article surveillance (EAS) systems.

Traditional pedestal systems interfered with cardiac device functioning, especially when the devices were in prolonged close proximity, the study found.

Prof Stevenson said: “Doctors must educate patients about the potential dangers. It is particularly important that patients do not sit or slouch in a chair or couch in entry areas. Electronic anti-theft systems are a part of everyday life. Patients are safe if they walk at a constant pace through the system.

“EAS gates that are obscured with advertising or goods for sale, or hidden in the floor with couches or chairs adjacent, are a serious concern and EAS manufacturers have a responsibility to ensure that retailers install them in such a way that they are visible and well marked.”
