Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

How long following a myocardial perfusion scan should I wait before visiting a person with a pacemaker?

How long following a myocardial perfusion scan should I wait before visiting a person with a pacemaker?

Immediately: There are no contraindications to visiting a person with a pacemaker after you had a nuclear stress test. You can visit them anytime as the radiation does not effect the pacemaker. ...Read more

What is the purpose of a myocardial perfusion scan?

Nuclear stress test: This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine. ...Read more

What are the risks in having a myocardial perfusion scan?

What are the risks in having a myocardial perfusion scan?

Stress associated : A myocardial perfusion scan is performed in two steps. One injection of a radiotracer at rest and another at stress ( either treadmill or pharmacological stress test with adenosine, regadenoson, dobutamine, dipyridamole). Only few skin reactions have been reported with the radiotracer injection. Risks are more associated with the stress used for the test such has angina, headache, nausea... ...Read more

Could you have a myocardial perfusion scan if you suffer from myoclonic dystonia?

Probably not: In most clinics, you will need to stay still for 20 to 30 minutes while being scanned. If unable to do this, you may want to investigate other imaging tests such as stress echo or cardiac ct. ...Read more

Is it safe to be around kids after a myocardial perfusion scan?

Is it safe to be around kids after a myocardial perfusion scan?

Small exposure: The doses of radiopharmaceuticals used for these scans are usually relatively low dose. However thallium (half life 2.7 days) gives more radiation than technetium sestamibi (half life 6 hrs).Radiation reduction depends mainly on two factors time and distance. If you do not stay close to child for prolonged time then radiation exposure is reduced.Growing children more sensitive to radiation. ...Read more
