Hi, I was given Alprazolam for rapid heart rate in 2009 but it got worse. Was given beta-blockers, this made it worse than before and caused severe pulminary hypertension of 56mhz. Now on Diltiazem, but has not fixed problem. Thyroid is fine. Take multi liquid vitamins.I cannot take "any" meds or eat food with seasonings without it affecting heart. If I get up from laying down position goes from 94 to 163 heart rate, so I stay in bed a lot.I do not drink caffeine or take drugs, and I don't have high blood pressure. I've lost 30lbs since having this condition. Anxiety meds make heart beat faster. It is 2011 and still dealing with this. What is causing this?
