I just wanted to say thank you to everyone who replied to my last post and gave me advice.
I bought the AliveCor Kardia straight away and as suggested asked my GP for the missing medical documents.
I saw the head consultant, who is a Cardiologist and EP, and low and behold yes there is evidence of the Afib before the Cardioversion.
Then I told him I had the AliveCor and he was like ' you have the app and readings..let me see' and I was able to show him what has been happening.
At the moment I am experiencing a lot of sinus tachycardia 130 plus, even on the meds. He said catch the Afib and we will talk Ablation.
So thanks again for all the suggestions!
