@jmarsh If you were to ask me what I think of your position on this, I would say I agree with you. Any intrusive intervention carries risk, as do drugs. If you are not taking anything, and you have infrequent AND self-resolving episodes of SVT, then the worst thing you face is those infrequent episodes that fix themselves in an hour or two. No big deal. Once you introduce drugs, there's often a cost, even if it's not immediately apparent. If you undergo an operation, even day surgery, there's a risk (they'll still use propofol at least, and that's not nothing).

Everybody has to determine for him/herself what they're prepared to endure. Discomfort, worry, sleep loss, ruminating, higher blood pressure, more frequent urination, palpitations, breathlessness, maybe some syncope, but also future events that are possible as a result of age-related changes and morphological changes that may come in time due to the strains on the heart. Basically, if you can abide what happens and how it feels at the time, if there's no lasting anxiety, and no other worrying symptoms, dangerous ones, then.....why not let 'er ride?
