Hi, I recently was admitted into the ER for shortness of breath, swelling and heart palps. The ran blood work, did a chest x-ray, did an EKG and a Stress test with the treadmill. All came out normal however all symptoms are still there. My doctor spoke with a friend/cardiologist who wants to see me and do a Echo. My question is, wasn't all that enough checking for the heart? Would would an Echo tell that all the other testing didn't? and...would there be anything else they could have missed?? Thanks so much....Rhonda
