Background
- T wave abnormality that is associated with critical LAD stenosis
- Finding can be transient (persists for hours after pain has resolved and then disappears)
Criteria
- Biphasic T waves in leads V2-V3 OR symmetric, often deeply inverted T waves in V2-V3
- See example below
- A) biphasic pattern and B) inversion pattern
- See example below
- Prior history of chest pain
- Little or no cardiac enzyme elevation
- No pathologic precordial Q waves
- Little or no ST-segment elevation
- No loss of precordial R waves
Treatment
- Urgent cardiac catheterization
Example
- A: Biphasic pattern
- B: Inversion pattern
