What is diagnostic procedure uses a radiopharmaceutical to assess the patients heart function?
thallium test
How should patients be prepared for a technetium heart scan?
Two to three hours before the scan, technetium is injected into a vein in the patient's forearm.
What care should a patient receive after a thallium heart scan?
The thallium scan is performed in conjunction with an exercise stress test. At the end of the stress test (once the patient has reached the highest level of exercise he or she can comfortably achieve), a small amount of the harmless radioisotope.
What characteristics does a normal thallium heart scan have?
A normal thallium heart scan typically shows even distribution of the radioactive tracer throughout the heart muscle, indicating adequate blood flow to all regions of the heart. There should be no areas of reduced blood flow or "cold spots" which could indicate potential blockages or areas of reduced heart muscle function. The scan should also show normal heart wall motion and function.
What is the purpose of a thallium heart scan?
A thallium heart scan is used to evaluate the blood supply to the heart muscle. It can identify areas of the heart that may have a poor blood supply as a result of damage from a previous heart attack or blocked coronary arteries.
How should patients be prepared for a thoracoscopy?
Prior to thoracoscopy, the patient will have several routine tests, such as blood, urine and chest x ray. Older patients must have an electrocardiogram (a trace record of the heart activity) because the anesthesia and the lung deflation put a big load.
What test measures the flow of blood through the heart during activity is evaluated by injecting thallium into the bloodstream?
The test you are referring to is called a thallium stress test. This test helps evaluate the blood flow to the heart during physical activity by using a radioactive form of thallium injected into the bloodstream. It can help identify areas of reduced blood flow in the heart muscle, indicating possible blockages in the coronary arteries.
How often should heart patients get a flu shot?
Annually.
How is thallium scanning performed?
usually done after an exercise stress test or after injection of a vasodilator, a drug to enlarge the blood vessels, like dipyridamole (Persantine). Thallium is injected, and the scan is done then and again four hours (and possibly 24 hours) later
What stress test involves the use of radiopharmaceutical?
Thallium is the most common radiopharmaceutical used in nuclear medicine cardiac stress tests. Thallium shows how well blood travels through the heart in an active or stressful environment.
Which diagnostic procedure uses a radiopharmaceutical to assess the patient's heart function?
thallium test
What anesthetic agent should be of concern of the dentist of patients with heart disease?
