your discription of symptoms is suggestive of SVT
, are episodes frequent, l and during the episode what symptoms it produces ?
if produces significant symptoms like low BP
, loss of counsciousness then you straight away go for RFA, in mild or moderate situation you may take a trial of beta blocker/heart rate
However if frequency increases then you may ultimately need RFA.
you and your cardiologist should discuss thoroughly the pros and cons of early RFA.
hope this helps
