Finally, identify any EKG rhythm in 10 seconds of less. This podcast covers a SIMPLE 5 step method for rapid EKG interpretation and outlines the steps to help you quickly spot arrhythmias with confidence. There are many more factors involved in fully understanding EKGs but this simple 5 step method will help you know exactly where to start. If you work through the 5 steps in order you will be able to look at any strip any quickly notice abnormalities. You can view a PDF chart with essential heart rhythms and their criteria here.

Rate
With any strip, you should start with the rate which can be determined (on a 6-second strip) by counting the P waves or the R waves and multiplying by 10. You can also count the number of large boxes between R waves and divide 300 by that number. For example, if you count 5 large boxes between each R wave than your rate would be approximately 60 bpm. Identifying the rate is a good way to determine where the impulse is initiating and can quickly rule out sinus rhythm.
P Wave
The P wave is representative of atrial depolarization and the wave should have an upward direction, it should be visible, and smooth. If you do not see P waves or they are misshapen you are not dealing with sinus rhythm.
QRS Complex
The QRS complex represents ventricular depolarization and should be present. The complex should have a length of 0.06 – 0.12 seconds (1.5 – 3 small squares). Anything out of this range is abnormal.
P:QRS
Every P wave should be followed directly by a QRS. The ratio between P and QRS should be 1:1. This represents the appropriate route of impulse travel. Deviation or alteration from the impulse traveling from SA node through Purkenji fibers in the right direction may be identified with the P:QRS.
PR Interval
The PR interval represents the onset of atrial depolarization and the onset of ventricular depolarization and is a factor in determining how long the impulse is held in the AV node. PR interval analysis is helpful in identifying AV heart blocks. The PR interval should be between 0.12 – 0.20 seconds (3 – 5 small squares).
