everyone have heart palpitations before surgery that went away after
I had this very frequently before surgery. It was related to stress and worry over my weight. I would get flutters in my chest that could become intense at times, and made me feel like the room was blacking out. I never did faint though. I would also wake up in the middle of the night, bolt straight up in bed, and my heart would be beating out of my chest. This would last for 10 minutes sometimes. Once I went to the ER because an was so scared. The night time things may have been related to my undiagnosed sleep apnea. Anyhow....like I said, it was caused from stress for me. I had every test under the sun just to rule everything else out. This has since stopped entirely,as the source of my anxiety (my weight) is no longer a problem.
A friend of mine who was a cardiac nurse told me that when I felt like my heart wasn't beating properly, I should give a really hard cough, and that can sometimes get things back n track.
i took 2 kinds of medication for heart palpitations which i had for years (prior to surgery) was so bad when i was pregnant 27 years ago i had to take digoxin! i since weaned myself off the meds and haven't had the palpitations for a long time now. .. even before surgery. my doc said it wasn't weight related (surprise! everything else seemed to be)... i think it was stress related as marny indicated for herself... and yes when i coughed it seemed to stop.. i had been to emerg many times for this condition, put on IV and given a drug and wow.. what a feeling when they finally stopped.. good luck!
