i live day by day with the need of reasurrance , i have suffered panic attacks for almost three years now, i get bad palpitations and my heart speeds up a little bit, i know is the anxiety but when i get this symptoms more than once a day or two or three days back to back i start thinking of a heart condition, i have had ekgs, holters, an echocardigram, stress test, ct scans of all kinds and all its negative. everything seems to be normal, except that i dont feel so normal. i recently started psychotherapy, i take lexapro and cardizem for my palpitations but dont think its working too good, just had a talk with my cardio doc to see if we change it! im changing lex to celexa in a few days. i just wish i could be my old self again, just for a little of history this started happening 7 months after my fathers unexpected death.
