1. 1. Identify atrial & ventricular rates; o The same o 60 to 100/min. 2. Measure PR interval o <0.20 second 3. Evaluate QRS complex o should be no longer than 0.12 second 1

2. 4. Evaluate T wave o Upright & rounded o Inversion = ischemia 5. Evaluate ST segment o Flat o Significant elevation or depression = ischemia 6. Assess RR interval to evaluate regularity of rhythm 2
