What is Exercise Stress Test ?
Exercise Stress Test is a test that uses a change of EKG (a graph representing heart function) to determine how the heart muscles respond to stress. It is mainly used to diagnose and evaluate coronary artery disease, assess arrhythmia and heart rate response, and assess functional capacity. You will exercise (treadmill or bicycle) until you reach the target heart rate. This helps reveal how your heart works when you are active. Your blood pressure and heart rhythm (ECG) will be monitored throughout the procedure.
