Questions
What is the difference between どくん (dokun) and どっくん (dokkun)?
どっくん (with the small 'tsu') emphasizes an even stronger, more sudden, or more dramatic heartbeat than どくん. It feels much more forceful.
Can I use どくん to describe someone knocking loudly on a door?
No, どくん is almost exclusively used for the heavy thumping of a heartbeat or a strong pulse inside the body. For knocking on a door, どんどん (dondon) is more appropriate.
Is どくん associated with positive or negative emotions?
Both. It simply describes the physical sensation of a heavy thud in the chest. This can happen during a sudden scare (negative) or when feeling a sudden romantic thrill (positive).
