The Angel of Healing.
I guess I have had five of these over the last decade. It has been over three years and unfortunately I postponed one before my heart incident in April that might have detected a serious problem. Hence today and tomorrow.
The Stress part requires you to get your heart rate about 136 for over a minute. I reached 150 and kept it there. It is stressful, but being in shape helps alot. Then you lay very still while a picture is being taken by a machine sensitive to the radiation they injected when your heart was racing.
I stopped my meds for four days and was glad to get back on the one that keeps my blood pressure stable.
The result is a picture of your heart veins that shows any blockages and allows a safer intervention.
