I am panicking about heart health...advice?

Maybe this is crazy but I’ve been panicking lately about heart health. Getting myself checked, my 7yo checked, my 1yo checked. My husband was born with a heart murmur, maybe info I can use? Is this weird, do people do this? How do you push for this?

If you have a familial reason to do so then it’s worth getting checked out. However, no one believed my heart regulation issue until I was in my forties when it was finally caught on equipment and found to not be too problematic.
