I have a rather different outlook on ablations, after having had two. I would say that unless you are having really severe attacks I would say hold off having one (perhaps with the hope of EP's finding better methods).
I had my first in 2011 but within days was back in Tachycardia and A+E. The periods of fast pulse continued, but now they lasted for days rather than the hours they had been before. I was hospitalised several times and finally when all else failed (even a cardioversion) prescribed Amiodarone (hated taking that).
I eagerly awaited a second ablation, thinking that would make me better. I had that in June 2013 and the procedure lasted 6 hrs. I felt ill for weeks after with runs of tachycardia. For a few weeks after that I thought I was cured, felt so well and lively. Then wham in September back came the unstoppable tachycardia now constant and only halted by having cardioversions. I've had two since last October and am now awaiting a third as my pulse has been a more or less constantly 109 since the start of September. I can tell you it's very disabling to be in permanent tachycardia. I get breathless and tired if I try to walk very far, can just about manage going around the supermarket.
I have now been told that because of the scar tissue in my heart from the ablations it may have made it stiff. The outlook is I may always have this problem and my EP can do no more procedure wise. I am 63 and at times feel my life is over. My love has always been walking, now I can't walk round the shops let alone the coastal footpath. Sorry, but I've kept my mouth shut for such a long time re how ablations have worsened my heart condition, preferring to give hope to people having them.
As I said at the start of my post, unless you are having very debilitating symptoms, my advice (and this is from my experience only) would be look to your diet and fitness levels first, before an ablation. Lose weight and cut out processed foods. Once your heart has been tampered with - well enough said!
I want to make sure everyone is aware that ablations are not always the wonder cure and can make things worse. This post is just my opinion and experience, but a view that is rarely given on this forum.
