Your BBalance is able to measure your bioimpedance sending a painless electrical current through the body and measuring the body's resistance and reactance to this electrical current. If you have a medical implant (such as a cardiac implantable electronic device or CIED) it is recommended to deactivate the bioimpedance analysis to avoid any electromagnetic interference. These recommendations restrict using the BIA in patients undergoing heart failure or with nutrition disorders in whom BIA could be of major interest in detecting peripheral congestion and to help guide treatment. The present study was conducted to evaluate whether BIA caused electromagnetic interference in patients having CIEDs.
