I going to give you a gem, so pay attention! Here is the secret, don’t look at the overall rhythm. Instead, break down the rhythm and analyze individual components. At a minimum, analyze rate, rhythm (is it regular?), P waves, PR interval, and QRS complex. Learn what is normal for these individual parameters and what is abnormal. You can give me the craziest rhythm in the world and I’ll just break it down, analyze the individual components and interpret it correctly every time.
Commit the following to memory.
Normal Sinus Rhythm is as follows: Rate 60-100, Rhythm regular, P waves normal, upright, and only before each QRS complex, PR interval is .12-.20 sec, QRS morphology is normal and duration is less than .12 sec.
Sinus Bradycardia is as follows: Rate less than 60, Rhythm regular, P waves upright and normal in morphology, PR interval normal between .12 and .20 secs. QRS morphology is normal at .04 - .12 secs.
Continue and learn all of the basic 26 rhythms and their basic parameters and you will be able to interpret anything. If your not willing to memorize this stuff, don’t waste anyone’s time and quit now.
My personal opinion, it’s not how many rhythms you have practiced on, it’s knowing how to do it correctly and having the knowledge to do so. If you take a day or two to memorize the parameters, it will be easy sailing from here on out. Good luck.
