Answer #1

Answer is ventricular fibrillation is life threatening.

The other options are not associated with ventricular fibrillation.

Ventricular fibrillation is an abnormal heart rhythm in which the ventricles of the heart quiver instead of pumping normally. It occurs due to depolarised electrical activity. VF results in cardiac arrest with loss of consciousness and no pulse.

Ventricular fibrillation usually caused by inadequate blood flow to the heart muscle due to coronary artery disease during heart attack. Heart failure and cardiomyopathies patients are also at high risk.
