Does exercise affect ECG?
As you shift from rest to activity, the ECG system will record changes in cardiac activity. Periodically, the speed, elevation or resistance on the treadmill or bicycle will be increased to produce a corresponding increase in your heart rate.
Should I exercise before EKG?
Before you start exercising, the technician will perform an EKG to measure your heart rate at rest. They'll also take your blood pressure. You will begin to exercise by walking on a treadmill or pedaling a stationary bicycle. The rate of exercise or degree of difficulty will gradually increase.
