Persantine Thallium is a type of stress test performed in order to facilitate the imaging of the internal structure and activity of the cardiac muscles. Through the persantine thallium test, health professionals are able to visualize whether or not all chambers and adjoining vessels of the heart are able to receive an adequate amount of blood supply. It is especially utilized in order to identify any underlying cases of coronary artery disease.

Despite the fact that the persantine thallium test is a stress test, the examination is carried out without the need for the patient to engage in physical exercise. Instead, a medication known as persantine is administered through an intravenous route in order to illicit responses in the cardiac muscles and blood vessels that are similar to those that occur while a person undergoes any form of strenuous physical activity.

Before the examination is performed, the patient will be instructed to avoid consuming anything orally for at least 6 hours before the test, with the exception of drinking water. Smoking of cigarettes is also disallowed for a period of 6 hours prior to the test.

The test is done by introducing persantine into the patient intravenously, which is then followed by the induction of thallium in order to trace the flow of blood through the heart. The patient’s cardiac activity is then monitored through an EKG reading, and internal imaging of the heart’s muscles and blood vessels is achieved through a radiologic scan that details any blood vessels or chambers that were not able to adequately absorb or channel the thallium that had been administered.
