It felt like something inside me wound up and sucker-punched me from the inside out. The air around me got heavy.

WEDNESDAY, Feb. 15, 2017 -- While implanted defibrillators can deliver a potentially lifesaving shock to a heart that's beating erratically, patients often wind up in the emergency room or the ...

Two scientists have developed a low-energy defibrillation scheme that significantly reduces the energy needed to re-establish a normal rhythm in the heart's main chambers. They hope this ...
