Use the 5 step process to decipher (decode, solve, interpret) the correct rhythm. 1. Rhythm Is the atrial (p-wave) rhythm regular or irregular? Is the ventricular (QRS) rhythm regular or irregular? 2. Rate What is the atrial rate? What is the ventricular rate? 3. P-wave Is the shape of the p-waves the same or different? Are the p-waves negative, positive, various, or absent? How many p-waves are there for each QRS waveform (written in a ratio format)? 4. PR interval: How wide is the PR interval? 5. ORS How wide is the ORS complex?
