one idea I have is have you both ever or do you suffer from G.E.R.D or Gastroesophageal reflux disease that Could be one area for you both to check out.
Pain in that area can be caused by this problem.Obviously it would be good to find the cause of your rapid heart beats but for know obviously beta blockers for both of you and change them if they are indeed not working.
but for both of you,you need to start taking your own BP and resting pulses everyday and keep a note of this(same times every day)so that a true graph can be made from the data to see or to note any possible anomalies.*only trust good machines,like OMRON etc. as I bought a cheap one and it was"way off!".Now I bought an OMRON the same as the Docs use here in UK.
cheers. john.
Hi there, Iam a male 31 years old and I have the same symptons as you even when I go to the bathroom, I have been takeing atenenol 50 mg and recently it stoped working on me. I also just had a cardiac cath done and they didnt find anything. I also have alot of chest pain in the center of my chest like you, and I also have had all the cardiac test done also. So I think its time we both get a second opinion. Hope all is well and let me know you out come.
