Among patients with refractory ventricular fibrillation (VF), survival to hospital discharge was more frequent with double sequential external defibrillation (DSED) and vector-change (VC) ...

Depending on how the heart’s electrical activity appears on an EKG, a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the ...

Background: The availability of stored intracardiac electrograms from implantable defibrillators (ICDs) has facilitated the study of the mechanisms of ventricular tachyarrhythmia onset. This study ...

TRANSIENT arrhythmias are frequently encountered during catheterization of the right side of the heart. 1 They occur most frequently during manipulation of the catheter in the atrium as isolated ...

Shock-refractory ventricular fibrillation is common during out-of-hospital cardiac arrest. Alternative defibrillation techniques might improve outcomes in these patients. New research findings are ...

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 ...
