This is done by recording the electrocardiograph (ECG) of your heart while walking on a treadmill machine. It is useful in diagnosing ischaemic heart disease (reduced blood supply to the heart muscles due to coronary artery disease).
What is the purpose of monitoring an ECG during exercise?
(The Treadmill Stress Test) The exercise ECG is used to evaluate the adequacy of blood supply to the heart during exercise that may be symptomatic or asymptomatic and to assess the extent of limitation of blood supply to the heart in people with known coronary artery disease.
What is the purpose of exercise cardiac stress test?
Exercise Stress Test. An exercise stress test helps determine how well your heart responds during times when it's working its hardest. It typically involves walking on a treadmill or pedaling on a stationary bike while hooked up to an EKG to monitor your heart's activity.
What is the difference between resting and exercise ECG?
The resting ECG records the heart's electrical activity when the patient is calm, providing an overview of the heart's rhythm and conduction under normal conditions. In contrast, the stress ECG is taken while the patient is exercising on a treadmill or stationary bike.
What are the benefits of a treadmill stress test?
A health care provider may recommend a stress test to:
- Diagnose coronary artery disease. The coronary arteries are the major blood vessels that bring blood and oxygen to the heart.
- Diagnose heart rhythm problems.
- Guide treatment of heart disorders.
- Check the heart before surgery.
What is involved in a treadmill stress test?
In a stress test, you walk on a treadmill that makes your heart work progressively harder. An electrocardiogram (ECG) monitors your heart's electrical rhythms. The doctor also measures your blood pressure and monitors whether you have symptoms like chest discomfort or fatigue.
