Thank you for your reply most people have a-fib or sick sinus rhythms mine is being called Multi focal ectopic or something like that an the instability is what started the new tachy. I guess I will know more when I go in April I am just worried because everything I have read states that left ventricular ablation has a 50% stroke risk. If I don’t fix it my heart could become unstable and stop and if I do fix it I have a high stroke risk. Pacemaker was not an option. I just was hoping someone had that kind of ablation but I know the reason I was referred to Rochester MN Mayo was the risks and danger of what is happening. Feel damned if I do damned if I don’t at this point. I had no structural heart disease when diagnosed but the arrhythmia is wearing out the left ventricle. The cause is very unknown and one of the first tests at Mayo is an MRI to look at the heart for abnormalities. Just really scary, I know the patterns and issues were not common to the local cardiologist. I have faith in Mayo I am just worried probably normal.
