Can i request of the technician that when i take a cardiac treadmill stress test that the platform be on a horizontal level rather than an incline?

Less accurate test: The "bruce" protocol stress test was designed to increase the incline and speed every 3 minutes. A horizontal test may not stress the heart enough, before the participant has to stop. Sometimes signs of heart disease do not show until the higher levels, thus a non-standardized test might miss heart disease, thus being less reliable. You can discuss other types of stress testing with your doctor.
