Pacemaker patients could be at risk from wearing a smartwatch, after scientists found that electric signals from fitness trackers can cause deadly interference in heart devices.
Fitness gadgets work by sending a small, imperceptible current of electricity into the body, but researchers say it can disrupt the electrical pulses that keep heart implants functioning.
Experts from the University of Utah warn that the current could trick pacemakers into thinking the heart is beating correctly when it needs help, or give an unneeded painful electric shock to people with internal defibrillators.
Although the electrical current cannot jump though the air between people, it could flow from one person to another if they are touching, the researchers also warned.
It suggests that people could be at risk from partners, children or other family members if they share close contact.
Is this a “could happen but unlikely” sorta thing? Or a here’s the row of coffins already filled as a result of it thing?
