Branches of Coronary artery:

Proximal Left Anterior descending artery {LAD } Stenosis leads to Deep T Waves Inversion in the precordial leads ( V1 Through V4) as known as Wellens Syndrome.

Exercise induced transient inversion of the precordial U waves has been correlated with severe stenosis of the left anterior descending artery ( LAD).
