Implanted cardiac devices could be subject to tampering

News

Sensors made to pick up a heart’s rhythm in implanted cardiac defibrillators and pacemakers could be subject to tampering, according to research from the University of Michigan.

An announcement from Michigan highlights experiments in simulated human models, in which researchers demonstrated that they could forge an erratic heartbeat using radio frequency electromagnetic waves. They found that, theoretically, a fake signal, such as the one they created, could stop necessary pacing or induce unnecessary defibrillation shocks.
