The right matches are:
Ventricular fibrillation ==> Loss of consciousness and death
Two successive PVC's ==> Often asymptomatic
Bizarre ECG waves ==> Defibrillation is needed
.
Ventricular fibrillation is a violent and disordered contraction of muscle fibers, especially the heart muscle, in the ventricles. This systematically leads to loss of consciousness or death.
Defibrillation is a treatment by electrical shock of abnormal contractions of the heart fibers, in order to restore a normal heart rhythm.
Premature contraction of the heart alters the normal heart rhythm but is clinically undetectable or expressed as palpitations.

Answer:
The white matter fibers are the main component of the brain. Three different types of white matter fiber are :
Commissural fibers:
This fiber is important for the connection of the corresponding left hemisphere and right hemisphere of the brain.
Projection fibers:
These fibers helps in the connection of the brain stem and the spinal cord with the cerebral cortex.
Association fibers:
These fibers are associated with the connection of the brain regions within the same hemisphere of the brain.
