@instituteofhumananatomy: This is a real pacemaker inside a real human heart. 🫀 That wire — called the lead — threads directly into the right ventricular chamber and attaches to the heart wall. The pulse generator implanted in the chest sends electrical signals down that lead to control heart rate and rhythm. And here's the clever part — the generator is placed superficially on purpose. If the battery dies, replacing it is a simple procedure. The lead anchored to the heart? That stays put. Smart design meets incredible anatomy.
