- Hyperkalemia
- Pulmonary embolism (RV strain)
- Pulmonary hypertension, acute or chronic
- Pulmonary disease - hyperventilation, pneumothorax, pneumonia
- LVH with strain pattern
- RVH
- Bundle branch block (both left and right)

- CNS T waves (diffuse, deep)
- Arrhythmogenic right ventricular dysplasia (may also have epsilon wave)
- HOCM
