A treadmill stress test is an exercise-based test that is widely used by doctors and cardiologists to diagnose and determine cardiovascular activities, heart rates, and how the heart responds to external stress. It helps in evaluating how your heart handles exertion and pressures that are beyond the normal level of activity that you are used to.
This test is helpful and effective in detecting cardiovascular diseases and helps in evaluating your risk or potential of falling prey to chronic heart diseases. For instance, for a treadmill test, a patient might be asked to walk on the treadmill and can also be asked to use a stationary bike.
