Abstract

Overview

This study addresses the safety concerns surrounding the use of smartwatches and mobile phones near patients with Cardiovascular Implantable Electronic Devices (CIEDs). Due to the widespread adoption of these personal electronic devices, understanding their influence on CIEDs is critical.

Objectives

• Investigating the impact of mobile phones and smartwatches on the functionality of various types of CIEDs.
• Assessing the risk of electromagnetic interferences by these devices.

Background

There is a significant concern that electromagnetic interferences from commonly used personal electronic devices can pose threats to patients with CIEDs.

Methods

148 patients equipped with CIEDs from four different manufacturers underwent 1,352 tests utilizing devices like iPhone 6 and Apple Watch A1553 placed at varying proximities to CIEDs.

Findings

• The occurrence of electromagnetic interference caused by these devices was extremely rare, showcasing a single instance involving a dual-chamber pacemaker.
• However, telemetry interference induced by the iPhone 6 was observed in 14% of subjects, highlighting a potential risk under specific conditions.
• No interferences were reported with the Apple Watch.

Conclusion

While the overall risk posed by the iPhone 6 and Apple Watch to CIEDs is low, precautions should be advised when these devices are in close proximity to implantable medical devices due to the potential for telemetry interference.
