Some of you will remember recently about all the test I've had done due to chest pain I was experiencing. I've had a nuclear stress test and an MRI of my heart. After the stress test they said I had anterior ischemia but then after the MRI they said no, I was fine. Well, I just went to the doc to see about all this heartburn I've been having. I saw a new doc since my primary physician moved to a different hospital (I wasn't too happy with him anyhow). So he listens to my heart and then goes back and listens a second and third time. He tells me I have a heart murmur. Shouldn't the MRI have picked that up? Anyhow he wants me to have an echo cardiogram done. Anyone have any input on the difference between an MRI and an echo? I thought the MRI should have been definitive???
