Detail:
I went to bed early , heart seemed to have thudded a bit recently , it was noticeable that night . I put in earplugs because the people in the flat upstairs were making a noise . I could hear my heartbeat & realised I had 2 heart rhythms , the usual & 2 extra beats every 3rd , about 50:50 . I laid there for about an hour , to make sure I wasn't imagining it & it wasn't going away .
Got a couple of buses to the walk-in clinic I've used before & have great confidence in - for gastric flu & impetigo . They said they didn't have the equipment to diagnose me , so another 2 buses to the local A&E . I had a cardiac trace , 2 PVC's in the 13 seconds , my description of an extra double beat every 3rd confirmed . They gave me a copy of the heart trace to take to my GP , they had ringed the abnormal beats & written the diagnosis on it , which was very helpful . Had bloodtest ( U & E's ) & chest X-ray . They seemed to be OK .
This took 5 hours , lucky I brought a book to read ! 5am , too late to go to bed so I got a minicab home , washed & changed , ate breakfast & commuted to London . I worked 7am-3pm , at least I can still pull an all-nighter if I have to !
