This article describes me to a tee. I also was diagnosed with panic disorder in my teens. It started with abnormal heart rate while regular walking. I would run home and lie down until it stopped. I am a very anxious person most Fibromyalgia and MEare type A superman types. But at 20 my doctor put a holt moniter on me for 3 days . He told me I would need a heart pacemaker in my 50's (now) because at times especially at rest my heart would beat at 50 beats. A minute? I still don't know if this is related to my illness, or just a fluke. The jumping and restarting heart beat complaint is still there but not nearly as bad on klonapin and Prozac and I can't lie on my left side as its brought it on also. I will be drinking salt water tomorrow. Ironic because I've been hospitalized a few times for dehydration and low potassium hypokemia I believe they said. And have all the pituary deficiencies just try to get your medical to pay for Testesterone? And my deficiency was severe, along with Hgh, low ins1, and others, Rita
