They left bundles of petitions containing more than 100 000 signatures at prime minister J.G. Strijdom's office doors.

From the AV node the electrical impulse travels down the Bundle of His and divides into the right and left bundle branches.

Once the bundle (meaning a group of strings or wires going in parallel directions) goes through the ventricle muscle, it divides into two bundle branches, the left bundle branch and the right bundle branch.

Specifically, blocks that occur in the right or left bundle branches are called "bundle branch blocks," and those that occur in either the left anterior or left posterior fascicles are called "fascicular blocks," or "hemiblocks."

Some authors consider left bundle branch block (LBBB) to be a technical bifascicular block, since the block occurs above the bifurcation of the left anterior and left posterior fascicles of the left bundle branch.
