I've been having symptoms of sharp chest pains,dizziness,feeling faint,memory loss,stomach cramps,severe headaches. A recent MRI of my heart was within normal range although it revealed a slight enlargement of the right ventricle and the tiscupid valve had mild regurgitation of 21ml and 16%. A 24hr holter monitor was within normal varients although it stated a tendancy toward bradycardia. My heart rate was between 40 and 128 and was less than 60 ---43% of the time. Could anxiety cause these symptoms even when i sleep ,waking me up with chest pain and fluttering feeling in my chest. I've been seeking an answer to these symtoms for a while. I often cough up blood along with black mucous also. I need some kind of relief soon.
