I was diagnosed with SVT 18 months ago and had an ablation which unfortunately I was in that percentage that didn’t take care of it. I was like you stressing about it, wondering when the next episode would be prior to the ablation. After the ablation I just thought that was it and I was good. 4 months later occasional episodes started but I wasn’t anxious about them. My cardiologist felt that since the episodes were very sporadic medication wasn’t needed as I could stop them immediately with valsalva maneuver and I chose not to under go another ablation. 6 months later he decided I should take Metoprolol and Flecainide and yet nothing had changed. Reluctantly I started them but 10 days in had to stop Flecainide due to severe acid reflux symptoms. Still on the Metoprolol which I want to get off of. I found this forum accidentally after the ablation and it really helped with being anxious about the diagnosis as numerous people had stated they had SVT for many years and don’t let it take over their lives and haven’t had treatment for it. In the past 7 months I have had 3 episodes which last less than 1 minute and as I said can stop them with valsalva maneuver. You may be one of the people an ablation stops the episodes. if you are considering it I wouldn’t hesitate as it was a relatively easy procedure.
