In brief: Vfib

Ventricular fibrillation causes the heart to not contract, blood flow to the body ceases and the patient will die if normal or contractile rhythm isn't returned.
Sweating is a response to low blood pressure. When blood pressure drops with atrial fibrillation patients may have sweating. Ventricular fibrillation long enough to cause perceived sweating unlikely unless reversed to better rhythm.

In brief: Sympathetic system

Ventricular fibrillation, which is usually a very short-lived event, usually occurs in a high sympathetic output state, at times the high sympathetic output actually is the cause for ventricular fibrillation but in any case the end result is the same.
As the sweat glands receive their innervation from this system of nerves, their output increases and the person sweats profusely.
