I lied at MEPS. Will they go back and look through my medical records?

It takes a special kind of stupid to admit that you LIED ON A GOVERNMENT FORM.

I would just keep your mouth shut. I am not big on lying but in a case like that, silence is the best.

My son was born with a congenital heart murmur that wasn't discovered until he was 3 years old. We were told by the pediatric cardiologist NOT to make an issue of it as 90% of infants are born with one most of whom 'outgrow' them as they 'self heal.'
The heart murmur never interfered with his activities as it was not the result of illness and he went on to engage in the adventures as his peers.
Sounds like your situation is very like my son's. Be straight with the cardiologist, tell him what you were told and I'm sure things will be just fine.

BTW, the doctors didn't tell YOU at the age of 6, they told your parents. How your parents handled the information is what's important here. I say you have nothing to be concerned with - an astute cardiologist will be able to tell the difference between damaged scar tissue and a healthy heart.

I had several times that I minimized the conditions and effects of being wounded in Vietnam. I did very well in Drill Sergeant’s School but during the last week one of the Instructors told me that I never stood at attention with my hips level. I told him that I was as straight as could. He looked at the scar when I was changing uniforms. He saw a 4” wide 7” across scar, shook his head and asked about passing a doctors exam before returning to duty. What did the Dr. Say? I told him that I wanted to stay in the Infantry. He wrote return to full duty and shook his head. I kept the same attitude until I could no longer perform at that level. It affected my back, neck and legs. The duty helped me to stay in better condition and stretched muscles well. The heart murmur was never a problem until I needed a heart valve replacement at age 71.

The Doctor at my initial physical told me that I had a heart murmur but that it went away when I took a deep breath. So I passed and spent 4 years active and 22 1/2 Reserve Duty always in Infantry assignments. So do not worry about this.

Who told you you had a heart murmur at age 6? How many people remember everything at age 6, let alone understand, do you? Don't play dumb. If the meps doctors find something wrong, they'll tell you. But DON'T try to BS around it. I knew somebody who wanted to get out of the Navy so bad (he was a problem child) and he went to a psychiatrist in his hometown to create a phony psychiatric disability (pre-existing condition) so he'd get discharged on that. That's fraudulent enlistment. Don't pull that stunt. Just let cardiologists do their tests and take it from there.

His heading under his name states that he is a Civilian and Possible Recruit. He needs to remain a Civilian and raise his hand to Serve and Protect the United States of America. I wonder

About 1/2 way through AIT, it was discovered that one of the soldiers was found to have had a fraudulent enlistment. Another listed his name as Jimmy when in fact it was James. Both were kicked out of the Army and gone the next day.

Lying is never a good option, you would be better off by telling the truth. And yes they can go back through your medical records to look for related medical conditions.

Wow! Really? Your post should’ve said, “Doc at MEPS found a murmur. I totally forget as a child I was told I had a murmur but would grow out of it. What do I do now?”
Better go to your recruiter & say you believed you doc.
