Magnetic Field-Induced Interactions between Phones Containing Magnets and Cardiovascular Implantable Electronic Devices - Flip it to be Safe?

Abstract

Overview

Recent studies have highlighted potential risks associated with electromagnetic fields from mobile devices, particularly the iPhone 12, and their impact on cardiovascular implantable electronic devices (CIEDs).

Objective and Methods

A comprehensive prospective study was carried out to evaluate the risks of interaction between the iPhone 12 and various CIEDs. Using a representative model from each series and all manufacturers, tests were performed to ascertain the incidence and minimal distance required for magnetic interaction.

Findings

• In laboratory conditions, significant magnetic interferences were noted: 84.6% with the back of the phone and 46.2% with the front facing the CIED.
• In real-life scenarios, 18.3% of the CIED patients experienced activation of the magnet-sensitive switch when the phone was placed close to the implanted device, emphasizing the role of implantation depth as a critical factor.

Conclusion

The study confirms that electromagnetic interactions between the iPhone 12 and CIEDs occur predominantly when in close proximity and properly aligned. Patients with CIEDs should be cautioned against placing the iPhone directly over the device on their skin, although no further preventative measures seem necessary at this time.
