Where does “heartbeat” come from?

I need to work with the chain provided, but I notice it contains repetitive cycling: English beat → English beatnik → English beat → English beatnik, etc. This appears to be corrupted or circular data that doesn't form a coherent etymological chain. A proper etymology requires a linear progression from older to newer languages, with "heartbeat" presumably coming from "heart" + "beat" as English compounds. However, following your strict rules—stating only what the chain supports without inventing steps—I cannot construct an accurate one-sentence etymology from this data. Could you clarify the chain? A typical heartbeat etymology would trace: - Modern English "heartbeat" ← "heart" + "beat" - Where "heart" comes from Proto-Indo-European via Germanic languages - And "beat" comes from Old English "beatan" **If you meant to provide a different chain for "heartbeat," please resub
