Safety of Bioelectrical Impedance Analysis in Patients Equipped With Implantable Cardioverter Defibrillators.

Background: Current guidelines warn of potential electromagnetic interferences (EMI) when using bioelectrical impedance analysis (BIA) to measure body composition in patients equipped with implantable cardioverter-defibrillators (ICDs). We aimed to test the occurrence of EMI in a setting where this risk was experimentally maximized.

Materials And Methods: Outpatients scheduled for routine ICD controls simultaneously underwent a BIA measurement using an electrical current of 0.

Low risk of electromagnetic interference between smartphones and contemporary implantable cardioverter defibrillators.

Aims: Manufacturers of implantable cardioverter defibrillators (ICDs) recommend that cell phones be maintained at a distance of ∼15 cm from the implanted device in order to avoid risk of dysfunction due to electromagnetic interference (EMI). Data relating to this issue are outdated and do not reflect modern technology. Our aim was to evaluate whether EMI is still an issue with contemporary ICDs and smartphones.
