Please will someone advise to how you tell the difference between anxiety and a heart attack. Google doesn't help at all. I had an ECG done and all is fine but my heart rate is always in the 80s. Sometimes I wake up during the night and battle to go back to sleep my heart will be beating fast but then slows down. I have back pain from the tension but if you look this all up it says you having a heart attack.
Please help thank you
