I am a female and 28. Ok so since about January i have been having heart attack like symptoms. I have seen a cardiologist and electrophysiologist.they have ruled out anything associated with my heart. i get a sinking feeling when it starts and then my heart races and then i get dizzy,short of breath, and the pain starts. this happens off and on throughout the day. i also feel sick to my stomach. my heart rate goes up over 200 sometimes, i dont hyper ventilate, and the pain is on the left and radiates to the center and right. my left arm hurts, my neck or jaw hurts, and i often develop a headache. i have been checking my blood pressure and when it starts my blood pressure spikes. I never feel good. i have been to the er soooooo many times and im sure they are tired of me. occasionally i have had blood work with low potassium and a high d dimer. but blood clots have never been found. Im in the process of getting results for an adrenal tumor and sleep apnea. im just curious if anyone can think of something to look for that im not. Oh and I also got tested for anxiety was put on antidepressants and that didn't work nor did any anxiety meds. Beta blockers didn't help or blood pressure meds. I have had an event monitor halter monitor,tilt table, echoes, and a bunch of other stuff done. And I have seen anxiety counselors. Today I went back to the 're but the doc thought it was GERD....well since I left the pain started again and nothing works and I haven't even eaten anything yet. I don't throw up or have the acid reflux burps. I am getting so tired I don't know what to do. I'm ready to give up. I am a little over weight and I do have asthma and diabetes. But my a1c is 6.4 and my asthma is well controlled. I'm just at a loss.
