LVH is normal in athletes, but pathological in non-athletes. It usually occurs pathologically in patients with untreated hypertension, although there are other reasons. You must get it investigated. Echocardiography will confirm presence of LVH, although not necessarily the cause.
LVH is not necessarily disqualifying. In particular, if there is no pathology associated with it, stopping exercise will cause the condition to slowly resolve (but add more complications
) If you have high blood pressure and LVH, then treatment for the former will also help resolve the latter.
In a small number of cases LVH may be caused by something other than hypertension or exercise training. In these cases there will be significant cardiac pathology involved, for example cardiac myopathies such as aortic stenosis. These will usually show on an echo.
Chances are you have nothing to worry about, both from an aviation medical and a health viewpoint, but of course it must be investigated.
