I am on Keppra xr and vimpat and I have been having pressure in my chest and wierd heart beats like my heart is beating real hard sometimes. I am now having to get tests done for my heart and everything has came out normal so far. The heart problems are getting worse. I think they are anxiety but my mom has some heart condition and of course I can't remember the name of it but it is genetic. Can seizures cause heart problems or what? I don't understand all this and am confused. Im also taking Lexapro but shouldn't that help anxiety? Does anyone else have this same problem? Im now starting to get pains in my chest like if I have real bad indigestion sometimes they come without the indigestion.
