What are Premature Atrial Complexes (PACs)?
Electrical impulses that originate in the ventricles and initiate a late impulse
Electrical impulses that originate in the atria and initiate an early impulse
Electrical impulses that originate in the atria and initiate a late impulse
Electrical impulses that originate in the ventricles and initiate an early impulse
What is another name for Premature Atrial Complexes?
PVCs
PACs
PAVs
PTCs
What is meant by "Add-on dysrhythmia" in the context of PAC criteria?
They create a new rhythm

Constant except for early complexes
Constant except for late complexes
Never constant

Randomly varying
What is the shape of P waves in normal complexes?
Uniform shape
Flattened
Notched
Biphasic
How might P waves appear in PACs?

What happens to the P wave when an impulse comes from a different location?
It remains the same
It becomes uniform
It has a different shape
It disappears
Where might a premature (early) P wave be hidden?

Why is the PR interval considered normal in PAC criteria?
Because the delay in a SA node is normal
Because the delay in a AV node is normal
Because the delay in a bundle branch is normal
