Good to know that tricuspid regurgitation shouldn't be a big issue, I also didn't know that was very common. A few other people I talked to said the same thing about being tall and thin, I'm 5'11" 170 lbs so that could explain it. Thank you so much for your help!Your tricuspid regurgitation (TR) has been labeled "physiologic" so I wouldn't worry about that. "Trace" or "mild" TR is extremely common, almost to the point of being a "within normal limits" finding in a young, otherwise healthy person.
In my experience at NAMI, the most common cause for an abnormal axis on an EKG in the standard issue SNA/SNFO was that the corpsman inadvertently reversed the left and right arm leads, but that's pretty easy to diagnose when reviewing the EKG. Second most common cause was that the candidate was a tall, skinny kid whose heart was positioned more vertically in the chest and pulled the main voltage axis toward the right.
