@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?

@jmarsh Hi. I had similar goings on. About 8 years of SVT. No drugs just amlodipine to bring down heart rate/blood pressure. Then I passed out right when one started as I got the drug. Hospital overnight observation for big lump on back of head. So no driving at that point. Ablation was only answer. It was scary waiting, got shingles from stress so another 3 week wait. EP created event, showed Afib and SVT. 6 weeks out, no issues at all but on Eliquis until EP clears me. On Holter monitor now looking for events of any kind. I have felt nothing. Happy it’s over no more SVT. And hopefully no Afib either. Oh , I have Factor V Liden blood issue evidently for my 79 years I wasn’t aware of is one reason he kept me on blood thinner til I get with a hematologist about that. Felt great in 2 days and on with my 79 yr old self. Just my situation, everyone had a different thought. Great info on this site.
