The cardiac cycle - it's one of those topics that often make students cry. And I understand why. It's usually taught as this VERY complex graph (shown above) and can be overwhelming for even smart students (like you)

I don't like that. In fact - I hate it. That's why I put together this free resource. I want to help you understand it. I want you to feel confident when your professor asks you "complicated" questions. I want you to be able to explain it to him/her in detail - because you understand it thoroughly.
