Safety of Bioelectrical Impedance Analysis in Patients Equipped With Implantable Cardioverter Defibrillators
Abstract : 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 0.8 mAmp at frequencies from 5-100 kHz. ICD sensitivity levels were set to maximum levels while therapies were temporarily inactivated. The device electrograms were monitored in real time to detect sensed and/or visible EMI during BIA measurement. RESULTS: A total of 63 patients equipped with single-chamber (n = 13), dual-chamber (n = 18), or biventricular (n = 32) ICDs from 5 major manufacturers were included. No EMI were detected by the ICDs in these patients, nor were any artifacts visualized during real-time electrogram recordings. CONCLUSION: BIA can be safely performed in patients equipped with ICDs without cardiac monitoring. Current guidelines should be updated accordingly
