Interpreting the Electrocardiogram

1. Identify atrial & ventricular rates; o The sameo 60 to 100/min.

2. Measure PR intervalo <0.20 second

3. Evaluate QRS complexo should be no longer than 0.12

Steps to Follow (cont.)

4. Evaluate T waveo Upright & roundedo Inversion = ischemia

5. Evaluate ST segmento Flato Significant elevation or depression

= ischemia6. Assess RR interval to evaluate
