A Peek at Cardiac Stress Tests

The stress test is the one tool that cardiologist use with which to diagnose heart disease. Doctors work with trained technicians for optimal results when performing stress tests. Different tests are required to diagnose different conditions and they all have their very own unique sets of requirements. The degree of reliability for a cardiac stress test is influenced by the test as well as other conditions.

Sometimes people exhibit symptoms that are common among different diseases; in these cases regular stress tests may be prescribed.

The degree of reliability of the isotope stress test depends on several important factors.

For example, a target heart rate must be attained, and of course the image quality must be sufficient. When these important factors are present, then a stress test of this kind can allow for a reliable diagnosis in roughly 85% of patients with coronary artery disease. Considering that there are other variables that play a role in the accuracy of this test, 100% infallibility cannot be achieved. There are a wide range of variables that can affect the accuracy of a diagnosis, including false positives.

It is also important to note that tests have limitations, and that is also true for cardiac stress tests. For example, plenty depends on achieving the best heart rate. Stress tests involving imaging are solely dependent on the quality of the images. There are certain natural circumstances and situations that can impact the quality of images too.
