T- wave inversion in the inferior lead aVF or III, as was mentioned in the absence of symptomology, and cardiac enzymes Troponin C and such, is generally physiologic, in fact many normal individuals present with tachyarrythmias, bradyarrythmias, and ST segment and T- wave inversion, axis deviaions and even runs of V-fib yet there's no EKG to continuously monitor them. if you don't pass after a retest you may require electrphysiology testing 'cath lab' to completely rule out pathology---a bit ridiculous with out angina or cardiomyopathy--- at least for the non flying
edited to add inferior is lead III... forgot an I
