Welcome aboard. I am not sure you gave us enough info re your concern. "Fast correction was done the urine output only about 300ml for 3 days can this created cardiac infarct." I am not sure what your dx was and what the correction was that you refer to.
2 GM = 2000mg. Potassium prescribed by physicians is in mEq.
So 39.10 mg = 1 mmol = 1 mEq. The relationship is generally unique for each
substance and has to be computed from atomic weights, and valence observed in
In my calculation you may have received approximate 50 mEq of Potassium. This is truly a question of your physician that prescribed the medication and he should also be able to advice you re your cardiac question.
I wish you the best of luck and please remember I am not a physician.
