I'm taking my ACLS class in 2 weeks and am nervous about the rhythms I'll need to know. I'm a new grad, and in school we spent 1 class on it. I've studied EKG basics, but Im not good at recognizing rhythms. I'm so confused about all the different leads, and how in some, negative deflections are normal. I get that its all about the electrodes, the direction of the impulse, traveling to negative or positive, but.... I still get so confused. I'm studying from EKGs Made Incredibly Easy, which is helpful. I'll study the ACLS book when it arrives. What should I focus on in my studies? Which Rhythms? VF, VT, SVT, asystole and what else? I'm finding the concept of algorithms relatively easy. The rationales. Like, give epi, then amiodarone to prevent REfibrillation. So I'm pretty OK in that area. The rhythms are causing me a lot of anxiety though. For example, I can't tell the difference b/w A-fib and premature atrial contractions. And some rhythms, I'm thinking "is that the t wave or the p?, when there is only one positive wave after a qrs complex. So confused
