What are the various stages of stress test, for example, Level 4.  What are the various levels of activity that make up Level 1, Level 2, etc. and how many levels are there. Thank you!

Dear Marcy,
Each stage refers to a level of exercise.  There are many different types of exercise protocols and each one has a different speed and treadmill grade for each stage.  I have attached below a chart comparing the various protocols.
I hope you find this information useful.  Information provided in the heart forum is for general purposes only.  Only your physician can provide specific diagnoses and therapies.  Please feel free to write back with additional questions.
If you would like to make an appointment at the Cleveland Clinic Heart Center, please call 1-800-CCF-CARE or inquire online by using the Heart Center website at www.ccf.org/heartcenter.  The Heart Center website contains a directory of the cardiology staff that can be used to select the physician best suited to address your cardiac problem.
