ECG ANSWER and INTERPRETATION
This is classic ECG of Wellens syndrome (Pattern A), demonstrating characteristic biphasic T waves in V1-3.
- This ECG pattern is highly predictive of a significant occlusive lesion of the LAD.
- The biphasic T waves are a marker of reperfusion and may occur after an aborted anterior STEMI.
- Despite often being pain free and having normal cardiac enzymes at presentation, these patients are at risk of sudden LAD re-occlusion leading to massive anterior STEMI and are best managed with early angiography and PCI / CABG.
