Admission ECG showed biphasic T waves in leads V1-V3 with inverted T waves in leads V4-V6 (Figure 1A). Coronary angiography revealed a critical proximal LAD stenosis and then angioplasty with stent placement was performed successfully (Figure 1B).

Electrocardiogram demonstrating deeply inverted T waves in leads V1-V4 (A), and coronary angiogram showing 95% stenosis of proximal left anterior descending artery (B).

T waves in leads V1-V4 (Figure 2A). Troponin T was found to be minimally elevated (peak troponin T value was 0.055 ng/mL). On coronary angiography, tight stenosis was observed in the proximal part of the LAD and then the lesion was successfully opened with stent deployment (Figure 2B).
