Implanting a defibrillator just weeks after a heart attack does not improve a patient's chances of survival, according to an international study. The researchers suggested instead that patients wait ...

LANSING — A new type of heart defibrillator was implanted for the first time in Michigan during a December procedure at E.W. Sparrow Hospital. The device is able to give a more normal life to people ...

Using light pulses as a model for electrical defibrillation, scientists developed a method to assess and modulate the heart function. The research team has thus paved the way for an efficient and ...

Oct. 8 -- WEDNESDAY, Oct. 7 (HealthDay News) -- Implanting a defibrillator in the first weeks after a heart attack does not improve survival, a major European study shows. Fewer deaths from sudden ...

A new observational study suggests the position in which responders initially place the two defibrillator pads on the body may make a significant difference in returning spontaneous blood circulation ...

The Resynchronization–Defibrillation for Ambulatory Heart Failure Trial (RAFT) showed a greater benefit with respect to mortality at 5 years among patients who received cardiac-resynchronization ...

Despite advances in defibrillation technology, shock-refractory ventricular fibrillation remains common during out-of-hospital cardiac arrest. Double sequential external defibrillation (DSED; rapid ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...
