In brief: Milliseconds
When there is a delay in conduction between the atria and ventricles, av block is present.
If the delay exceeds 200 milliseconds, 1st degree block is present. If delay progresses to intermittent interruption of conduction, 2nd degree block is present. If there is complete interruption, so the atrial and ventricle beat independently, 3rd degree block is present.

In brief: Rhythm problem
Av block is atrioventricular block.
The heart beats in a synchronized manner because we have an electrical system. The generator of the electical pulses is the av node. If this becomes "sick" there is no impulse generated or there are other malfuncitons of the av node or the electrical pathways and the hear may slow to dangerous levels. A pacemaker may be needed. A cardiologist is needed.
