Radioisotope Images of Blood Flow Through the Heart Muscle

Each portion of this picture is in two parts. The top part of each section shows the radioisotope-laden blood after a treadmill test. The bottom portion of each section shows the same after a night's rest and while at rest. Because the bottom views don't have any "holes" in them, we know I didn't have a heart attack. Intervention at this time saved my life, or at least saved me from significantly greater risk.
