This manuscript analyzes the prognostic implications of implantable cardioverter defibrillator (ICD) shocks in high-risk patients with heart failure. The authors included 811 patients with heart ...

A lifesaving shock from an implanted heart defibrillator provides relief that a crisis was avoided, but new research suggests it can also be a sign that more trouble is ahead. A study found that heart ...

Every minute spent waiting for a first shock from a defibrillator cuts the odds of surviving cardiac arrest by 6%, a new Dutch study finds. Photo by Mikhail Nilov/Pexels Oct. 28 (UPI) --Every minute ...

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 ...

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 ...

It is well known that acting quickly in the event of a cardiac arrest is important, but what does a quick initial shock with a defibrillator mean exactly for patients' chances of survival? Researchers ...

Electric shocks delivered by subcutaneous defibrillators are equally effective compared to shocks delivered by conventional transvenous defibrillators, according to a study published in the journal ...

Oct. 28 (UPI) --Every minute spent waiting for a first shock from a defibrillator cuts the odds of surviving cardiac arrest by 6%, a new Dutch study finds. "Our research shows that every minute of ...
