fibrillation

An AED may be able to restart a heart in ventricular fibrillation or ventricular tachycardia (I suppose we can quibble over what 'restart' means).

Ventricular fibrillation is not a death sentence, but your claim made it out to be so, and needed to be corrected.

The slightest movement can send a victim's heart muscle into wild spasms of ventricular fibrillation.

A defibrillator gives a large shock to the heart to knock it out of a dangerous rhythm such as ventricular tachycardia or ventricular fibrillation.

In the case of more severe cardiac fibrillation, it will take a period of time before you actually lose consciousness depending on the severity.

It is a form of ventricular fibrillation (V-Fib), not mechanical damage to the heart muscle or surrounding organs, and not the result of heart disease.

You can't have been in cardiac fibrillation if you were awake.

I would recommend it to elderly family members, but they have atrial fibrillation, and I heard omega 3 can exacerbate it?

The sort of semi-procrastination that occurs when you're still being productive (because you're still learning), but you realise that you've gone from studying waveforms to ventricular fibrillation.

A smartwatch with a pulse sensor could easily detect an arrhythmic pulse, which can be a symptom of atrial fibrillation, one of the most common causes of strokes.

The only point of defibrillation (automatic or not) is to stop ventricular tachycardia or ventricular fibrillation (electric rhythms that don't cause effective heart contractions), and kick-start a sinusal (normal) rhythm.

The other wonky thing with my health is that I have had Vagal Atrial Fibrillation (VAF) in the past (which is rare for someone in their 30s).

Your heart going into fibrillation is not the cause of your heart problems, but treating the fibrillation can save your life - whatever the "cause" of that fibrillation.

I think by "restart", he meant the useful shorthand of "restore a useful rhythm, restart the heart as a pump instead of a tasty snack", and only in the case where the heart was in ventricular fibrillation or tachycardia.

Fibrillation is basically different parts of the heart firing randomly, with the effect that not much blood gets pumped.

Fibrillation is a problem, but so are electrical burns.
