Quizplus · Accepted Answer

The persantine/thallium test is a diagnostic test used when a patient is unable to engage in physical exercise to raise the heart rate. It involves intravenously administering a medication (persantine) that dilates the coronary arteries and simulates the effect of physical exercise on the heart. The patient's heart function is then monitored using a radioactive tracer (thallium) and imaging technology. This test can help identify areas of the heart that may not be receiving enough blood flow, indicating potential blockages in the coronary arteries.
