Does ECG stress test ST depression and ECG stress test ST segment mm lead mean the same?What st segment mm lead (number) would be considered very low,low,moderate,high and very high during (Bruce) stress test?Thank you.Billy
mm stands for millimeters and is a measurment of the ST segment changes. The interpretation of stress tests is a technical issue and beyond the scope of this forum. A good book that can give you this information is Chou's Electrocardiography in Clinical practice.
