Smartphones may set off defibrillators and pacemakers
PATIENTS with a defibrillator or pacemaker should not keep a smartphone in their chest pocket, researchers say.
A study of 300 patients with a cardiac device found that when a smartphone was placed over it, one patient’s implantable cardioverter-defibrillator (ICD) began oversensing.
