Hi,

It seems like your doctor is just being cautious by ordering another exercise stress test, this one with imaging. Sensitivity of en exercise ECG is lower than that of stress imaging. The test you'll be having is much more expensive than the one you've just had, but also more accurate, yielding more information than an exercise ECG stress test. It provides a good assessment of blood flow and detects any ischemic areas within the heart.

Do you know which test you'll be having? Your doctor might decide not to put you on a treadmill. If you are physically unable to exercise, pharmacological agents will be used to simulate exercise. I don't think people can fail this particular test - one actually doesn't do anything but lie on a gurney. A drug, such as dobutamine is used to simulate exertion. There are doctors close by if needed. Prior to the test, an IV injection of a tracer is given. The subsequent imaging shows the distribution of a radiotracer throughout the left ventricle. Any areas not receiving adequate blood flow can be easily seen. The ventricle volume and ejection fraction are also determined. Images are taken again at rest. The test is an easy one to have compared to others. The only side effect I had was a nasty, long-lasting headache from the tracer. There is a small amount of radioactivity during the imaging process.

I've had both types of stress tests. Regular stress testing in unsuitable for people with abnormal baseline ECGs and in certain cirumstances, including chronic kidney disease and long-standing hypertension. The accuracy of testing in such settings varies greatly. I read that for this reason, an ECG stress test is a waste of time in people with chronic kidney disease.

I don't think you will fail this test so don't worry. Let us know how it goes. Good luck!

well i had no pain when i was on the treadmill but i think i felt a little fluttering while jogging but i was real nervous before i even had the test adn had a lot of anxiety.

i do have mvp and i get pain when im just sitting or not exercising but i have a treadmill at home i go on and never really felt any pain exercising, just when im not exercising. its weird

As you say, the symptoms can be really strange and inconsistent. Pain comes and goes and so do all the weird sensations. While some of these manifestations are brought on by exertion, others are not. I wonder if it is "normal" to experience several different types and levels of chest pain.

As for the ECG abnormalities, unbalanced electrolytes (K) will cause changes and so will some rx drugs. That is why people are asked to stop their beta blocker a few days prior to the stress test.
Your doctor did not elaborate on his statement because he is not sure about the reliability of the ECG. That is why a better test is needed. You'll be fine.

The nuclear stress test allows the cardiologist to pin down the location of possible cardiac arterial blockages.

I've had three or four of these procedures. They are not the golden standard that angiograms represent, but are good at picking up ischemic areas that may call for an angiogram.

Good luck.
