Thanks for writing us..
It seems you are sufferring with gastritis
LAD and t inversion in lead iii may be present normally also..
but if you are above 45 year of age with either smoker, Hypertensive or diabetic you should go for
ECHO and TMT test.
because your pain pattern ( pain in hand and jaw) makes a suspicion of anginal pain.
I will be happy to see you after reports
