Inverted T Wave - Lead III

Allow me to preface this by advising that I will be getting my butt into a cardiologist's office next week, but would be grateful for any feedback, opinions, or other banter!

Summary:  Moved to Florida in May and had first annual physical today, inclusive of EKG.  EKG showed a negative T-wave in Lead III.  What gives???

Details:  40 year old male, no history of arrhythmia, screened negative for HCM 7-8 years ago (EKG & Echo), completely asymptomatic.  Ironman triathlete, 12-15 hours of typically high intensity training weekly without any issue.  No family history of cardio issues.

Medical:  Hashimoto's Thyroiditis (hypo); previously had somewhat elevated LDL levels, but calcium score test showed Zero risk;  Full blood panel a year ago showed normal LDL levels.

The doctor (today) was not able to properly explain potential reasons for my inverted T wave and simply ordered an echo.  I'm not a medical professional, but have been surrounded by medicine my entire life - ironically even becoming passionate about HCM screening.  

Any theories?  False reading?  Perhaps bad lead placement?  HCM and I'm going down on my next bike ride?

Appreciate any and all thoughts.

Chris

Negative T in III is an extremely nonspecific finding.

Often it's normal and can be caused by anything from taking a deep breath to being a normal variant. Some people have a leftward axis from having a muscular left ventricle. In that case, both QRS and T could be negative in III

But it can also be caused by a strained right ventricle from high pressure in the pulmonary arteries, so you should ask your cardiologist.
