In most contexts, “AFK” doesn’t refer to anything related to health or heart rate. It’s a common internet abbreviation that typically means “Away From Keyboard.”
However, there’s a possibility you might have encountered “AFK” in the context of art. There’s a street artist named AFK, and in some descriptions of his work, “HF” is used alongside “AFK.”
Without more information, it’s difficult to say for sure what “Hartfrequentie afk” means. Here are the two possibilities:
- Most likely: It’s a misunderstanding, and “AFK” refers to internet slang, not heart rate.
- Less likely: You came across a reference to artist AFK, and “HF” might be a code used in connection with a specific work.
If you can provide more context about where you saw “Hartfrequentie afk,” I might be able to help you narrow it down.
