Just thought i'd update on my recent experience for those interested.
I had my first diagnosed AF episode in December 2013. It was persistent (24/7) until i had an electrical cardioversion in May 2014. I was taken off drugs shortly afterwards and have been AF & drug free since then. I have returned to swimming & running on a regular basis
However on Tuesday (April 2016) it returned during a run. I quickly realised what had happened. Resting HR was in the 120's and rhythm was erratic.
I decided (maybe wrongly) to see what it was like the following morning after a sleep. In the morning the HR had dropped into the 60's but the rhythm was still erratic, so i took myself off to A&E.
Although they confirmed slow AF they were reluctant to intervene immediately, rather they wanted to send me away with warfarin and an appointment with the cardiology dept. I didnt want this!
With the knowledge i have picked up on this site and elsewhere i made numerous comments about the chemical cardioversion. The triage GP went and sought further advice and came back saying they would take me in and go with the chemical cardioversion. Hurray!
Due to my HR being relatively low they didnt think amiodarone would be appropriate but gave me instead an increased dose of flecanide
30 mins later, during a routine BP check my ECG flatlined to zero ( i could feel my vision clouding) then immediately reverted to sinus rhythm at my usual resting HR. (Question does flecanide usually work like this ie flatline HR?)
After a couple of hours of further monitoring i was discharged, with a follow up appointment planned with the cardiology dept
Fingers crossed for another 2 years AF free
