Can you describe the chest pain more fully, like where exactly you feel it in your chest, the circumstances when you feel it (more likely at rest or when you're running, for example), anything you can do to make it feel better--or worse? Is it a stabbing pain, or is it more like a dull ache?
How much chest pain did you have while doing the treadmill test? If the pain had been totally disabling, you would *not* have been able to keep running after being ordered to do so. The test is designed to test your maximum physical limits while watching for warning signs. If something dangerous had been seen on your readout, the test would have been stopped at once, for medical, ethical, and legal reasons.
BTW, collapsing at the end of this test is *normal*--sometimes they have a big guy or two to physically catch patients who are maxed out at that point.
About the false positives, I think you need to schedule a real appointment with your cardiologists to discuss *exactly* how this term is being used and what it means in your particular case. As it stands, it's too vague to make sense of.
