Abstract
Background: Smartphones have become ubiquitous, nearly seamless extensions of ourselves and our daily lives. With >300.000 implanted cardioverter defibrillators (ICD) implanted each year worldwide and the continuing rise of smart device and wearable use, the question of interaction between smartphones and ICD is an important one.
Objective: The purpose of this study is to describe the possible magnet interference of new smartphones generation on ICD and has the potential to inhibit lifesaving therapy.
Method: We have tested in vivo the shock inhibiting therapies using two smartphones (iPhone12 and P30 Pro) on 51 patients. Tests were performed on a patient wearing a Medtronic and Boston Scientific ICD. Amongst the patients, 24 had an Medtronic ICD model and 27 the Boston Scientific ICD model implanted. The tests were conducted in hospital office. A correct position of the smarthphones was signaled by a beeping sound emitted by the device and by repeated device interrogation,
Result: With the two models of smartphones correctly positioned, the tested inhibited the shock therapies for both ICD models in 42 patients for the entire period for application (82.3%).
Conclusion: Patients with an ICD should be warned that some newer models of smartphones equipped with magnets (MagSafe), can disable their device inhibiting its lifesaving functions.
