I have been having shortness of breath. It feels like I cant get enough air in my lungs, or if they have shrunken somehow. I have cardiac arrhythmia, and I had a weird episode where my heart was racing for almost an hour and a half. I went to the local acute care and they gave me an ekg, which was 'normal of abnormal'. I have had ekgs done before, and compared to the ones previously done, this one has changed a bit...I dont know how exactly. I was short of breath the day before I had this 'episode' and it is now 24 hrs after the episode, and I am still short of breath as I am typing this message.

Please help

thanks
