After lots of tests and conversations with the EP I agreed last week to go for the pace and ablate offered. I have been offered a date on the 26th of this month. I thought that I would have to wait for six weeks and so felt quite shocked when I received my admission date today. He thinks that I will have a good chance of relief of this terrible breathlessness, which only happens when I move from my chair. It will be a dual chamber pacemaker which will increase my chances of success. I will post again if it is successful.
Thank you all for your support whilst researching which was the best route to go down.
