- Make basic measurements, evaluate for ischemia, infarction, and hypertrophy.
- Diagnose clinical conditions based on criteria described in Chapter 20.
- Evaluate clinically.

Clinically-Based Critical Thinking: Interpretation
There is sinus tachycardia associated with low voltage. Possibilities include COPD (with sinus tachycardia due to hypoxia or sympathomimetic therapy), or a large pericardial effusion, or tamponade. The presence on an anterior QRS is consistent with pulmonary hypertension. The low amplitude affects the T waves and P waves as well.
