What causes a rapid heart beat with panic attacks?
Patient: in two of last three nights I awakened from a dream to notice a fast pulse & I could feel my heart beating ; then I went into a state of shivering for a while. I had a large normal looking stool after I settled down. In very early morning I noticed another bout of fast pulse and then I ll settle down. I don t typically have a stool at night. I ve routinely urinated at night without to date having been medically tagged (e.g. all lab results normal) ; and so I again urinated twice before this bout of shivering hit me. But this shivering is a novel event for me?! Doctor: Hello,  Regarding your concern, I would explain that your symptoms could be related to a panic attack or irritable bowel syndrome.   Anyway, before coming to this conclusion, I would recommend performing some tests (complete blood count, PCR, ESR and a stool analysis).   Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Ilir Sharka,  Cardiologist
