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 ...

Ventricular fibrillation (VFib or VF) and ventricular tachycardia (v-tach or VT) are two types of heart arrhythmia that occur in the heart’s lower chambers called the ventricles. The ventricles ...

The secondary end point of favorable neurologic outcome followed a similar pattern. It was 2.8 times more likely among patients initially with VT/VF and 3.8 times more likely among those with no VT/VF ...

Implantable cardioverter defibrillators account for one-third of the decrease in cardiac arrests caused by ventricular fibrillation in North-Holland, according to research in Circulation, an American ...

The incidence of ventricular fibrillation or pulseless ventricular tachycardia as the first recorded rhythm after out-of-hospital cardiac arrest has unexpectedly declined. The success of ...

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

Numerous factors can contribute to sudden cardiac death, from underlying disease after myocardial infarction to genetic variants that can claim young lives. In 'Bedside to Bench', Stanley Nattel ...

Note: ECG = electrocardiography, LAD = left anterior descending artery, STEMI = ST-segment elevation myocardial infarction. These cases raise several questions: Are these true syndromes or simply ECG ...
