One way to hold this word: someone at the front, holding a steady speed that everyone else moves to. Look at the shape of the word and it is already there — pace plus maker, the thing that makes the speed. In a race that is a runner nobody expects to win; in a chest it is a patch of cells, or a small machine, at the right rate. The pacemaker never does the moving. It only says how fast.
From the word’s history
The word is simply pace plus maker: the thing that makes the pace.
這個字就是 pace 加 maker：定出步調的那個東西。字面和意思幾乎完全重疊，所以拆開來看最好記。
