I just had a stress test/abnormal...the doctor said I have a depression/indention in my heart..then walked out..I am scheduled for a thalium treadmill and eccocardiogram...I was in a serious auto crash almost two years ago...I brused my chest area bad...I had a stress test done after the accident because the medics report some kind of cardiac problem at the accident site..My cardio doctor said there is a change from the first stress test to the one I just had....What does a depression/indention indicate? Could this be a result of the crash?
