Technically, a resting EKG is produced in the first step. In the following, the patient is subjected to a physical effort on the treadmill, using a well defined international protocol, called the Bruce protocol. Walking speed and incline on the treadmill are gradually increased every 3 minutes and the EKG is continuously recorded during the whole procedure. Blood pressure is also recorded every 3 minutes, using a sophisticated blood pressure monitor.
Usually, the test is continued until the target heart rate is reached or it may be discontinued due to occurrence of symptoms or EKG abnormalities, indicating an underlying cardiac problem.
Don’t forget to bring along sports footwear (trainers, sneakers), when you are scheduled for a stress test.
