My first cardioversion lasted 19 days, I then went to my GP to get ECG confirmation and he decided to send me to A+E (I also had a chest ache during cycling) at Sheffield Northern General where I was able to get them to do a second cardioversion that night. The chest ache was investigated and not thought to be an issue. I am a keen cyclist who used to do up to 100 mile trips. When persistent AF started in September I cut this back to 60 miles max with no steep hills. After the first cardioversion on the 21st November I took things very steady and gradually increased back to my last ride of 60 miles where I was feeling a bit poor and my heart rate monitor confirmed I was back in AF. I visited my GP the next day. I am now back at home after the second cardioversion, in NSR, but feeling nervous about doing any cycling or exercise for a while. I have decided not to do any cycling for 2 weeks over Xmas, but with no exercise I will be a tetchy old thing! Any advice or comments please. I am 67.
