Advantage
of doing exercise stress test: This kind of test will help revealing the
following:
The length of exercise: The patient continues to exercise until they achieve a specific target heart rate based on age. This will help to determine exercise tolerance
Identify symptoms during exercise: shortness of breath, chest discomfort, dizziness, or fatigue and weakness. Any one could suggest underline heart disease.
Blood pressure monitoring during exercise:
High diastolic pressure, suggest uncontrolled hypertension
A drop in blood pressure may indicate heart disease.
Identify arrhythmia or abnormal heart beats during exercise
EKG changes: EKG is monitored constantly during exercise, and any changes in comparison with the base line EKG, could suggest heart disease.
How does a regular stress test
work?
Symptoms and signs of heart disease may become more prominent by exposing the
heart to the stress of exercise. Reduced blood flow to a specific area in the
heart muscle, caused by a clogged or narrowed artery, may produce symptoms and
EKG changes..
How reliable is a regular stress test?
If the patient achieves target heart rate, regular treadmill is capable of
diagnosing 67% of patients with coronary artery disease. On the other hand 10%
of the patients may have a false-positive test (abnormal test in patients
without any narrowed arteries).
