I have suffered with what has been blown off as panic attacks since my early 20 s so for about 20 years now. I have at one point or another been put on every SSRI on the market and not a on e of them has ever helped me. My episodes start out of the blue when I am perfectly calm or at rest. It usually starts with a few PVC s(feel like my heart does 3 or 4 flips) then I get dizzy and its off to the races...my heart will start beating very hard and fast(up to 180BPM)...I never feelanxious til after this has been going on for several minutes. I have made several trips to the ER,some by ambulance over the last 10 years and the tachycardia and PVC s have been documented.but in the end I am always told panic attack but I really feel like there is more to this.. My question is this...I had some blood work come back abnormal 3 years ago while I was hospitalized for a flare of duverticulitis it was discovered that my Cortisol levels are way low and after a MRI/ MRA of my brain they found a pituitary microadrnoma that was the cause for the low cortisol and my HGH is deficient as well. Due to lack of insurance for a few years I have had no dither work up or treatment for this...could this be the culprit of my heart symptoms? I am not on board with the panic/ anxiety diagnosis ...just feels like something is being over looked. Thanks for your time. Missy
