Asystole
Why is defibrillation not effective when there is a total absence of venticular electrical activity in the heart?
When there is no electrical activity in the heart (asystole), the AED won't start the heart as drugs are required to start the heart. The AED will only re-set the heart from abnormal electrical activity (such as V-Tach or V-Fib).
What are ventricles doing atrial systole?
During atrial systole, the SA node ( power house for heart to keep on beating) is unable to send signals to ventricles. But heart has some back up power houses which take over, so the ventricles can still keep on beating but at a slower rate than normal during atrial asystole.
Why won't CPR restart the heart?
In order to restart the heart, from asystole, drug therapy is usually required; such as epinephrine, vasopressin, or atropine. A shock may still be applied. If the heart is in arrhythmia, it will require a shock to reset the heart. CPR will not bring the heart back to a normal rhythm, or restart the heart. CPR will circulate oxygenated blood until help arrives to administer shocks or drug therapy.
What two heart rhythms are considered lethal?
There are a variety of them. There's ventricular fibrillation, ventricular tachycardia, and of course "asystole". There are also other lethal dysrhythmias that can deteriorate into forms of the aforementioned rhythms like 3 AV Block, agonal, Accelerated IVR, etc. http://skillstat.com/Flash/ECGSim531.html check out this website and look at some of the rhythms. click play when it comes up.

By the time Asystole sets in, the brain has gone a good 20-45 minutes without oxygen. Asystole is when the heart has stopped long enough to become depolarized.
