What to expect
Arrival
You'll be connected to monitoring equipment and given clear instructions before starting.
During the test
You'll typically walk on a treadmill that gradually increases in effort while your heart rate, rhythm, and blood pressure are monitored. If you can't exercise, a medication option can create a similar effect.
Duration
Plan for about 45-60 minutes including prep.
After
Wear comfortable clothes and proper walking shoes; you're free to go home and resume normal activity once monitoring is complete.
