Anxiety causes strong and missed heart beats. Perimenopause causes some too. Heart attacks not so much...
I am a woman of 50ish, a bit fat, fairly fit, well and healthy - until suddenly I wasn't -
I have had a heart attack (Dec - so fairly recent). Mine started with a heavy pressure tight-band feeling around my chest, pain in the right side of my face so bad I could feel each individual tooth nerve, pain then went deep into my chest and over the cap of my left shoulder.
I knew instantly what the problem was. I was still able to walk around, and rang an ambulance etc. I had had no previous signs, just those occurring within 20 min.
Everyone is different, but most of the people I met in the hospital with the same trouble knew. They knew they were having a heart attack, they were not umming and ahhhing about what was up. There was a deep feeling of dread, that I - and they, had something very very very wrong indeed and needed it seeing to immediately.
