Left Main Coronary Artery Pattern

Report:

Sinus rhythm 90/min

Probable left ventricular hypertrophy

ST/T changes c/w infarction/ischæmia

Main left coronary artery lesion pattern

Comment:

The LVH voltage is seen in the frontal leads (R1 + S3 > 26 mm, RaVL > 13 mm) and in RV6 > RV5. LVH probably accounts for the (unchanging) QS complexes in V1-2.
