Morphology
The meaning is directly compositional: 'artificial' (man-made) modifies 'pacemaker' (a device that regulates the heart), yielding 'a man-made device that regulates the heartbeat.' There is no idiomatic shift or metaphorical extension and similar formations exist in many languages, so a B1 learner who knows both constituents would readily understand it.
Etymology
Artificial pacemaker comes from the idea of a pacemaker in races, a runner who sets the 'pace' for others. The device is a 'made by people' artificial machine that makes the heart keep a steady 'pace', so it is called an artificial pacemaker.
