You know how sometimes you learn about something and suddenly you can't stop seeing every instance of it being done completely wrong? Yeah, that's me and ECGs right now. I've learned the structure of a normal ECG output, and so now I can't see (incorrect) fictional ECG output without going "Wait a second, that's not how those work!"

Here's an ECG from a game, with a rough scribbled on normal heartbeat for comparison. Notice how the game's ECG lacks a T wave and seemingly is missing that Q interval (or it has no P wave and 2 RS complexes). This bugs me intensely.
