Had my Paroxysmal AF cured only now to have developed SVT

Had my 2nd ablation for paroxysmal AF at the end of September. Seems to have worked this time, however after seven days of having my 2nd ablation I had SVT which I have never suffered from before in my life. I had attacks over three days, the first two reverted within half an hour then on the third day after bending over to pick something up I had another attack. It went on for two and a half hours resting heart rate of 187 bpm. At this stage I was concerned so phoned my GP who told me to dial 999. I was taken to Royal Bournemouth Hospital and after several attempts with various exercises to revert they decided to do a cardio version using Adenosine which worked the first time. My consultant then put me back on Propafenone 150mg three times a day and started me on Bisoprolol 2.5mg once a day. I seem to be tolerating the Bisoprolol quite well, only had side effects for the first three days of taking them and haven't had any SVT attacks since. However after seeing my consultant two weeks ago he now wants me to have a third ablation to cure the SVT, I asked him if the SVT attacks could have just been caused by the ablations I had just had done and was just the heart going through the healing process as there was only two months between having the 1st ablation and the 2nd one. He said no, SVT originates from the right hand side of the heart AF originates in the left and my SVT was now documented from the ECG's I had done so it was definitely SVT and not AF. I am pretty disheartened by this as it now seems I have had one arrhythmia cured only to have developed another one. Has anyone else on here had the same problem.?

  • Hello Dale, Sorry to hear that you developed a different type of arythmia, it must have been disappointing when the EP said it wasn't because of the ablation. This happened to me but the other way around. I had to go to the ER last month because I had SVT with heart beat of 220. They gave me an injection of Adenosine (it's called Stryadine over here in France). They told me it would stop my hear beating for three seconds then I would revert to NSR. Instead of stopping the tachycardia, it put me into Afib which lasted about 30 hours. I saw and EP the next day and he explained that about 30% of people have SVT and 1% of those people go into another kind of arythmia when trying to stop it. I was disappointed to know that I was one of that 1%. It seems you may be part of that 1% too but in the opposite direction. He told me that if I wanted to have an ablation to stop the Tachycardia, it just might stop the Afib, too. I've only had two tachys in 20 years, the first stopped on its own. I had one small bout of Afib in 2009 after a very bad ferry crossing when I'd been sea sick for a long time then the second was after the Adenosine injection. My EP said I might not have gone into Afib had it not been for the injection which made me think that the next time I get a tachycardia , I'll try to stop it at home rather than have another injection. So, it seems your EP is right in saying you would need another ablation but so soon after the first one seems a bit much surely you need time to heal from the last one. If you do go ahead with another one, though, the chances must be really good that you'll be free at last both from the Tachycardia and the Afib. Best Wishes to you. Trish

  • Hi Trish, thanks for your reply. Yes I thought it was quite soon to have a third ablation too. In fact I turned the first date down which was Thursday just gone as it was only six weeks since my 2nd ablation. My EP did say that there is a 98% chance of success with curing the SVT the 1st time and that it is a simpler operation than the AF ablation. I am a bit nervous though as this one has to be done under sedation, not general anaesthetic which I had for the last two. They want to do an EP study first which cant be done under general anaesthetic.

  • I've read a lot about these ablations done under sedation and everyone says they would have them again no problem and they had very little discomfort during the operation or after. I would focus on the fact that your EP has told you that it's 98% successful AND the fact that it is a simpler op than for the AF ...which means you'll be arythmia free in no time..... that would be great!

    All the best Dale, try and relax and not worry too much, I'm sure you'll be fine , there's no reason why you wouldn't be but I DO understand your disappointement. Trish

  • I have had three ablations with sedation and remember almost nothing, which I feel is a bit of a pity as some of it must be very interesting. The first (2011) was for SVT which disappeared but has just crept back again. I've been free of it with my beta blocker doubled. The other two ablations (March 2014 and December 2015) were for AF.

    Three ablations in the space of a few months seems a bit of a marathon, Dale, but it's possible that it will not take long to sort the SVT.

  • Thanks for the reassurance Rellim, I suppose I should be grateful I've not had to wait very long for my ablations.

  • Some EPs have long waiting lists!

  • I dont know if this will help you, but I had SVT then AF and flutter, was ablated 6 weeks ago, and all veins were ablated at the same time, I was under for 3half hours which was quite a long time.

    I am doing really well now, not a peep and feel as if I have my life back again, wonderful is all I can say, I can understand your disappointment but hey its great to feel wonderful, so don't even hesitate, go for it and good luck
