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. If there is any clogged or narrowed artery,
leading to reduced blood flow to a specific area in the heart muscle, leading to
starvation in that area and 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).
