I am suffering from palpitation since 2001 . Doctors sugested anti anxity drugs for me . such as frisium-5 tablets along with calaptin 40 tablets . with the above medicines I was going on with good except a few occations. now I am again facing palpitation at least once a day for a few minutes . kindly suggest me wheather I am a heart patient or neuro pshycreatic patient .

Hamdy from Egypt My sister has been suffering from papitations for some time. Shes may go back to hspital hours after geeting out. Last found was a fibroses of part of the heart muscles. Is this the end? Doctors here in Cairo say they do not know exactly what they can do. They ran an operation of what I can translate into ironing. Of course this is literal translation as I don't know the medical terminoogy for this operation. During this operation they discovered the fibrosis. Thank you in advance for replying.
