Does anyone else have VTs with a QRS axis inverted 120 degrees?

35 yr old male.Non smoker.light drinker. health concious.No drug use.
I have had non sustained VTs regularly since 1997 with an extreme axis deviation of  minus 120 degrees.
After 10 years they finally picked up my VTs as all other ECG tests proved normal.
Now they suspect RVOT but are testing for ARVC just in case.
My question is does anybody else have an exteme axis inversion of 120 degrees minus?
Is this dangerous?
What can cause this?
I have not had a MI,no chest pain,or syncope.
My cardiologist with 40 years experience has never seen this !
Please help if you can.
Thank you.
