You ever see a Pulmonologist to find out whether you might be an apnea case?
I had a solo flight of a-fib some years back. They wanted to put me on statins. A friend, a doctor of respiratory medicine, said “Wait until you’ve had a sleep study done.” I took that advice.
I’m the second-worst apnea case in my pulmonologist’s practice. Apnea was gonna kill me, and I had no idea.
If you’ve had a cardiac event, and your cardiologist didn’t find a root cause, get an in-clinic sleep study, and make sure you don’t have a deeper, undiagnosed issue.
They gave me one of those monitor devices that measures your pulse and respiration while you sleep a while back and I used it for a week or so.
Nothing ever came of it. My wife says I snore like a freight train, though.................
