My day yesterday: Went to A&E to get checked for nasty bout of irregular heartbeat. Got told high levels of troponin meant a "significant heart attack". 5 hours later - lab error. No heart attack!

Funny thing is despite being the world's most woeful hypochondriac - https://www.huffingtonpost.com/entry/im-an-internet-hypochondriac_us_5972adf8e4b0f1feb89b4395 … - I was surprisingly calm about having had a heart attack. (Partly because I didn't believe it!)
