Hey guys, I am learning about EKG's and I came across a sample one I just cant seem to ge as it looks NSR. Pic attachment Included in link , IMG 5782 — imgbb.com what do you guys think? Vent rate is 101. PR is 154ms. QRS Duration is 100ms. QT/QTc is 370/479ms. P-R-T axes 73,56, 58.

I know its Sinus tachy obviously but the thing says its an Infarct somewhere

Thx Help Appreciated

Q-wave in 1, and aVL looks pretty funky.  That would be my guess, a lateral infarct

The loss of r wave height in lead v3 is suggestive of possible age-indeterminant infarct. 

I can't really tell whats going on in avL aside from low voltage (too small), and the q wave in lead 1 looks a bit small and narrow to be of obvious significance (but again I cant seem to enlarge the pic to see it well). For whatever its worth though, ive heard that MRI studies have shown that avl often represents more of an anterior region of the heart than the lateral area its commonly said to represent, which goes along with the r wave regression in v3.
