The doctor wasn't present during the stress test. There was a technician there that would tell me when the monitor would register the palipatations. They didn't feel like much during the test compared to the alarming one I felt that prompted me to go to my Pcp. Its possible that i have been having them awhile and just didn't realize it. I often get dizzy when I stand but don't necessarily feel a heart palipatation. The technician said they were checking for heart murmer or mitro valve prolaps. He said the echo test will determine a abnormality in the heart valves or if the heart is enlarged. That's all I know for now until my echo test next week. Then the doctor will call to discuss the results. He did mention the possibility of putting me on a beta blocker.
