A new study recommends that people with cardiac devices such as pacemakers and implantable cardioverter defibrillators should be wary of smartphones, stating that close proximity to the phones can potentially disrupt functioning or cause painful shocks.

Electromagnetic interference from smartphones can cause implantable cardioverter defibrillators to deliver a painful shock to the user, according to researchers.
The research is being presented at the joint meeting of the European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC) and Cardiostim, taking place in Milan, Italy.
“Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working,” reports study author Dr. Carsten Lennerz, of the German Heart Center in Munich, Germany.
