What is an Adenosine or Lexiscan nuclear scan? It is similar to the exercise nuclear stress test except for the fact that Adenosine or Lexiscan is used to stress the heart. Adenosine is infused over 4-6 minutes, while Lexiscan is given over a few seconds.
How long is adenosine stress test?
How Long Will the Procedure Take? The entire procedure will take three hours.
Is adenosine A nuclear stress test?
For those patients who are unable to complete the exercise protocol, a pharmacological nuclear stress test is recommended. This testing method uses a drug to mimic the response of the cardiovascular system to exercise. Adenosine and Persantine are vasodilators used in pharmacological nuclear stress testing.
What is a adenosine lexiscan?
Lexiscan or Adenoscan are administered by intravenous injection during a cardiac nuclear stress test to patients who cannot adequately exercise. These drugs dilate the coronary arteries and increase blood flow so that coronary artery obstructions can be identified.
Can a nuclear stress test damage your heart?

But normal results from a stress test do not rule out the possibility of a future heart attack. This is because a plaque can still rupture, form clots and block an artery.
What is the difference between adenosine and dobutamine?
Abstract. Background— Dobutamine stress MR (DSMR) is highly accurate for the detection of inducible wall motion abnormalities (IWMAs). Adenosine has a more favorable safety profile and is well established for the assessment of myocardial perfusion.
Does adenosine stop the heart?
While adenosine can slow conduction through the AV node, it does not affect accessory pathways. In such cases, this can cause severe tachycardia that can deteriorate to a non-perfusing rhythm, leading to cardiac arrest.

What is an adenosine stress test?
Adenosine or Lexiscan Nuclear Stress Test. The blood flow through the blocked arteries- while adequate at rest- may not be able to keep up with the demands of a stressed heart. This can show up on the pictures of the heart taken after stress. This is the principle behind all the stress tests. The term ‘stress test’ is used for any means used…
What is the CPT code for adenosine nuclear stress test?
Adenosine nuclear stress test is performed by injecting adenosine drug in to the blood stream. The adenosine is the drug responsible for the dilation of nerves like during exercise. A radioactive agent is also injected inside the blood stream to check the activity. The CPT code for this test is J0152. Chemical Nuclear Stress Test CPT Code
How to prepare for adenosine or Lexiscan nuclear stress test?
Adenosine or Lexiscan Nuclear Stress Test. The preparation is mostly the same as for exercise stress test.
