So I don't see the difference between NSR and First degree AV block.  Are there symptoms associated with First degree AV block?

There usually are no symptoms for those who have First-Degree AV Block and is often discovered coincidentaly. The EKG reveals that thenormal P waves are followed by QRS complexes, but the PR interval is longer than normal,  > 0.20 sec...normal PR interval is 0.12-0.20 sec.
