Wellens’ Syndrome ECG Review

Wellen's phenomenon occurs when biphasic T waves are seen in leads V1-V3 OR deep symmetric inverted T waves are seen in the precordial leads. Both of these ECG findings are indicative of a severe proximal left anterior descending stenosis (acute or chronic). Note that there is NO ST segement elevation that occurs with Wellen's ECG changes.
