And to add to the post above, if it's been 2 years, I would think with sympoms like that you should be evaluated again. Take care, Ally
The EKG is a measure pf the electrical activity of the heart over a period of time, as detected by electrodes attached to the outer surface of the skin. IT can pick up abnormal rhythms of the heart, as well as evidence of an old myocardial infarction, an ongoing myocardial infarction, or active ischemia (restriction in blood supply to the heart). A stress test is a screening test for coronary artery disease. A stress test can show any abnormal blood flow to the heart muscle.
It is very possible for a stress test to be falsely normal in patients with coronary artery disease. If you are concerned about chest pain or discomfort, please discuss with your physician. It sounds as if you have a family history of coronary artery disease. With a normal stress test, the likelihood of coronary artery disease is low, but no screening test is 100% effective in ruling out disease.
