An electrocardiogram (ECG) stress test helps in monitoring the patient’s heartbeat, both at rest and during workout sessions.
During the test, a physician observes the patient, monitors workout and records the result until he or she attains the maximum heart rate. Today we bring you 10 facts about stress test.
The Stress Test
Physicians use stress test in evaluating the patient’s heart rate. The test requires the patient to perform exercises on an exercise bike or treadmill as the physician monitors his or her blood pressure, breathing rate, heart rate and feeling of well being.
