Wellens Syndrome Criteria (ECG)
Checks a 12-lead tracing against the Wellens criteria, the precordial T-wave pattern of critical proximal LAD stenosis.

Example
- T waves in V2-V3
- Biphasic in V2-V3 (type A)
- ST segment in V2-V3
- Isoelectric or elevated less than 1 mm
- Precordial Q waves
- No
- Precordial R-wave progression
- Preserved
- Recent anginal chest pain
- Yes
- Tracing taken while pain-free
- Yes
- Cardiac markers
- Normal
Result: Meets the Wellens criteria, type A: the precordial T-wave pattern associated with critical proximal LAD stenosis.
The tool opens with these values already filled in. Replace them with your own.
