I think it's great that you had an epiphany about the letters of an ECG. I hate to break it to you, this new knowledge is not going to help you understand Cardio any better. Knowing what they represent and any changes that can occur will lead to success.
PQRSTU is arbitrary. If they were named after colors, it wouldn't make cardio any easier, promise. Best of luck studying the heart and ECG's.
Also, hospitals now have STEMI codes and many have STEMI Coordinators (to train and monitor codes and other duties). STEMI of course refers to S-T elevated Myocardial Infarction. If you don't know what S-T is, you don't know what that code is being called for. I think nursing is a lot like the military -- loads of acronyms

This might sound like the biggest "duh!" you have ever heard in your life, but today I slapped my forehead and noticed it for the first time. The letters of the normal sinus rhythm, P-QRS-T-U are in alphabetical order. That's how you know if they are in the right sequence, or if one of them is missing! This knowledge makes it easier to memorize basic sine rhythm and a few of its variants, although it may not help with some of the really crazy dysrhythmias.
I can't be the first person to notice this little factoid, and it couldn't be accidental. Why is it that no one mentioned it in class? Or in the dozens of videos I've watched on YouTube? Or the websites, EKG games, or NCLEX practice test banks? My Med-Surg textbook says "the letters are arbitrary" and must be simply memorized.
Does this help anyone else?
