iPhone 12 MagSafe technology and cardiac implantable devices: assessment of the actual risk

Abstract

Overview

The study evaluates the risk of magnetic interference from iPhone 12's MagSafe technology on cardiac implantable devices such as pacemakers (PM) and implantable cardioverter defibrillators (ICD).

Background

• Cardiac devices are equipped with a magnetic sensor, which can be triggered by external magnets, leading to potential risks if activated inadvertently.
• The presence of magnets within the iPhone 12 introduces concerns about accidental activation of these magnetic switches.

Objective

This investigation aims to assess the effects of iPhone 12's MagSafe on a broad spectrum of cardiac implantable devices and to propose guidelines to mitigate risks.

Methods

Analysis of magnetic interference risk covering a diverse array of PMs and ICDs, highlighting the correlation between the magnetic fields of iPhone 12 and device activation.

Results

Findings indicate that magnets in the iPhone 12 can trigger these devices within 1 cm proximity, supporting the need for a safety distance.

Conclusions

Maintaining at least a 15 cm distance—advised by Apple and echoed by device manufacturers—is essential to prevent inadvertent switch activations.

Recommendations entail adhering strictly to safety distances and raising awareness among patients about the potential risks posed by proximity to iPhone 12 and related MagSafe accessories.
