There are always questions on the CCRN® exam over ACS.

These questions often describe a patient’s clinical presentation, give you a 12 lead ECG or describe 12 lead changes. Then expect you to identify what specific ACS the patient might have. Or vice versa.

For example: They might give you a specific infarct and then your answer choices will be various patient signs/symptoms and ECG findings.

Don’t worry -

You don’t have to be an ECG pro to do well. The key thing to remember here is the relationship between lead specific ECG ST elevation/depression, heart vasculature, and which ‘walls’ of the heart.

Let’s put this in terms of real life: What do you do when your patient starts having chest pain?

I’m not going to sugar coat it. The lead/artery/wall CCRN® topic is difficult. As a matter of fact, it’s one of the most difficult on the exam.

Unfortunately it’s one of those topics where good ol’ fashion memorization might be the best study strategy. With that being said, the video below does a great job of explaining these relationships in a fun way:
