EKG

The correct pathway for the conduction of an electrical signal through the heart is:

• SA node, AV node, AV bundle, Purkinje fibers, bundle branches

• AV node, SA node, AV bundle, bundle branches, Purkinje fibers

• SA node, AV node, bundle branches, AV bundle, Purkinje fibers

• SA node, AV node, AV bundle, bundle branches, Purkinje fibers

Which of the following terms indicates "fast"?
