In brief: Not true "block"
Two bundles of electrical tissue carry each heartbeat from the top part of the heart to the bottom--the "right" and "left" bundle branches.
When one of these doesn't conduct at all, or does so much more slowly than the other, it is a complete bundle branch block. When one conducts slightly slower than the other, it is called "incomplete" bundle block. This often is of no clinical consequence.

In brief: Slow conduction
The electrical activity in the bottom chambers of the heart take a certain range number of milliseconds to conduct (<120ms, commonly <100ms).
If longer than 120, it represents a slowing in the system, called a bundle branch block. If there is an appearance of some delay in the conduction, but doesnt meet criteria (>120ms) for a full bundle branch block, it is an incomplete bundle branch block..
