I'll have to go back and look at all of this thread. So it's SVT as opposed to atrial fib? Technically a. fib comes under the heading of an SVT but there are other SVT's. I have an idea of what would be prescribed here in the States. Of course, I don't know all the details and am not asking you for personal information. But the way I look at it is that the medication could be a good thing.
When the heart rate is very fast, not allowing for appropriate blood flow to the body, thus the symptoms like shortness of breath, dizziness, fatigue and chest pain among others. It also is quite a strain on the heart itself, meaning that if you don't get it under control with medication, you can have other problems.
Again, I have not read back all the way and don't know what the surgery reference is but if it is ablation, it can be quite helpful. I know life has no guarantees but I have a co-worker that had to have it. Not going to lie. She had to have it done twice I think, but she is back and working in the high stress environment of the ER.
At any rate, I know it's stressful. I also know that it is hard to come to a decision on what to do. I wish you well.
