Wearable fitness trackers could interfere with cardiac devices, study finds

Bioimpedance sensing technologies as used in smartwatches could affect implanted devices like pacemakers

Wearable fitness and wellness trackers could interfere with some implanted cardiac devices such as pacemakers, according to a study.

Devices such as smartwatches, smart rings and smart scales used to monitor fitness-related activities could interfere with the functioning of cardiac implantable electronic devices (CIEDs) such as pacemakers, implantable cardioverter defibrillators (ICDs), and cardiac resynchronisation therapy (CRT) devices, the study published in the Heart Rhythm journal found.
