i went to the ER because i was having alot of dizziness, clamy skin, even though i was sweating i was having chills so bad that i was shaking. i wasnt having chest pain, just pressure. they admitted me to the hospital.while there my blood pressure was dropping really low, and at one time my heart rate dropped to 28.they said i had bradycardia, and vertigo.they made me an appt. with a heart doctor. he sent me to have a tilt table test. the results were normal. my heart rate and blood pressure stayed normal.the second part of the test they give you medicine to speed up your heart rate. they had to triple the dose because my heart rate wouldnt get where they needed it to be.every since then i can feel my heart beating.next week i go to have a heart cath done, because they cant figure out whats going on. has anyone else had any of these problems, and could give me some answers. not knowing is driving me crazy.
