Hi. Yes, I remember you. I had mine a few weeks before you. Mine hasn't come back, but I get occasional shorts runs of something. I would assume it's SVT, but it could be VT. I haven't investigated it. Over the years, I've seen a few people who need to get it done again. So, it happens. Hope ypu can get it cleared up.
I don't think it is common for it to come back. It is possible for the scarring to heal over but I don't think it happens often. I read the younger you are when you have it done the more likely for it to come back because younger bodies are better able to heal themselves. It is possible you had another path somewhere else that is just now becoming active. That can happen too so just contact your doctor and see what they say. I am not sure what was going on in the hospital though was classic svt but more so maybe stress or simply your heart being sensitive after having had the svt episode. Low potassium may be part of the problem as well. Well best of luck. Try to take it in stride. Svt isn't life threatening just something to be responsible about so the less you stress about it the less toil it will take on your heart. Just do vasovagal maneuvers to get it to stop like bearing down and holding your breath or drinking a cold glass of water or head to the er if it doesn't respond or stop on its own. Best of luck. Keep us posted on how you are doing.
