Your problem here is twofold.
First, you feel that the first doctor erred and put you on beta blockers when you, in fact didn't need to be on them. You're worried about what, if any, long term or residual harm that you may have as a result of this medical "error."
Second, you still have palpitations, despite having been diagnosed as normal.
Answer to the first: Residual effects from Beta-Blockers? None. Your body today without beta-blockers is like you never even took them at all.
Answer to the second: You're still having palpitations, which, even if no WPW
, LGL, or any of the variants, exists; if you were on beta-blockers, it would probably help you. So even if there was an error, it was probably a helpful error.
Whether you're an anxious person, have excess hormones (like adrenaline
), have a valvular problem, or even really do have WPW, but one that is transient or intermittently seen; is something that needs to be further evaluated.
Your next step to absolutely rule out any cardiac cause is to see an EPS specialist (electrophysiology studies) where the palpitations can be forcibly reproduced and mapped. If they cannot be reproduced, then the problem lies elsewhere. If they can be reproduced, ie it really is cardiac in nature, you can then discuss with your doctor what options would then be appropriate (ie medication or ablation).
Either way, you and your doctors need to get into the habit of better communications as it is clear that you're dissatisfied with the care that you've been receiving.
