But if the nodes are connected, it’s still a single pump.
You’re merely choosing to redefine the terms. The nodes are part of the heart as a system - remove the nodes and well, the pump no longer pumps.
Your argument is like saying you can split a multi-cylinder automotive engine in half, leave the ignition system in place, and you have 2 engines.
No, you have one engine split in two, with it’s electrical timing system still determining how each cylinder maintains the exact same timing as before.
(Automotive engines are essentially air pumps with very specific timining mechanisms, as each cylinder’s output affects other cylinders, akin to the timing in a heart).

Well they’re not separated, so who’s really making the pedantic argument here?
