An exercise stress test, or stress electrocardiogram (ECG or EKG) records your heartbeat while walking on a treadmill. It is a way to track your heart’s response to exercise and assists your physician in evaluating the cause of your chest pain.
During the test, electrodes are placed on your upper body to monitor your heart rate. The treadmill exercise test starts out easy and then slowly gets more difficult. Your heartbeat and blood pressure will be monitored during and after the stress test. The test usually takes about thirty minutes from start to finish. You will need to wear a two-piece outfit and comfortable walking shoes for this test.
