He will use a Gamma Camera (a special camera used to capture images of your heart). However, if the viable component of the admixture of viable and scarred myocardium is reversible (stress-induced ischemia), then the defect will appear partially reversible (a region of non-transmural infarction sub-served by significantly narrowed coronary artery).

A negative ECG stress test doesnt guarantee you wont have a heart attack or other problem. It is mainly due to the blood perfusion insufficiency of the myocardium. With the administration of vasodilators for pharmacologic stress, the resistance vessels in the area subtended by normal coronary arteries dilate, diminishing coronary resistance and resulting in an increase in coronary blood flow nearly 4-5 folds above normal. These regions are represented as essential ischemic tissues that reserve the blood flow. When arteries get squeezed or become too narrow, they make it hard for your heart to receive enough blood and oxygen it needs to pump and the risk of heart failure arises. what does reversible mean?
