23
Q

TEE has a very high sensitivity for locating a blood clot inside the left atrium. True or false?

A

true

24
Q

Is sedation usually needed for a transesophageal echocardiogram (TEE)?

A

Yes

25
Q

What tests are known as Myocardial Perfusion Scans?

A

Nuclear Medicine Tests

26
Q

Radioactive tracer (Thallium) is injected into a vein.

A special camera, called a gamma camera, used to look at Thallium uptake by the myocardium.

This test is known as what?

A

Nuclear Medicine Test

27
Q

Combined with a vasodilator (dipyridamole or adenosine), this test can help determine if there is adequate blood flow to the heart during activity versus at rest.

What test is this?

A

Nuclear Medicine Test

28
Q

The medication used during the nuclear medicine test, dipyridamole or adenosine, increases the heart rate. True or false?

A

False.

The medication does not increase heart rate. The medication dilates blood vessels leading into the heart, increasing blood flow, therefore simulating exercise for patients unable to exercise on a treadmill.

29
Q

What test is preferred for those unable to exercise on a treadmill?

A

Nuclear Medicine Test

30
Q

One study found that a reversible defect found on exercise stress test studies was the most significant predictor of post-operative ischemic events. True or false?

A

False.

Nuclear medicine tests, not exercise stress tests reveal this information.

31
Q

A nuclear medicine test will provide what information on the report? (6)

A
  • Description: Thallium stress test
  • Indications: Chest pain.
  • Stress technique: exercised for 5 minutes
  • Image technique: injected with thallous
  • Image analysis: normal LV perfusion
  • Conclusions: Normal ECG stress
32
Q

What test is minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter?

A

Coronary Angiography

33
Q

What test involves a catheter being threaded into the heart through femoral artery, dye injected and is watched as it moves through the heart and coronary arteries?

A

Coronary Angiography

34
Q

What is the gold standard in evaluating coronary artery disease?

A

Coronary Angiography

35
Q

Important internal heart and lung blood pressures, not measurable from outside the body, can be accurately measured during a coronary angiography. True or false?

A

True.

36
Q

What test determines if patient may benefit from angioplasty or CABG?

A

Coronary Angiography

37
Q

Coronary Angiography is associated with a high complication rate. True or false?

A

False.

Low complication rate

38
Q

What portable device for continuously monitoring various electrical activity of the cardiovascular system for at least 24 hours (often for two weeks at a time)?

A

Holter monitor

39
Q

What is useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period of time?

A

Holter monitor

40
Q

For patients having transient cardiac arrhythmia symptoms, a holter monitor which can be worn for a month or more can be used. True or false?

A

False.

A cardiac event monitor can be used.

A

chest x-ray, or radiograph

42
Q

What test is used to diagnose many conditions involving the chest wall, bones of the thorax, and structures contained within the thoracic cavity including the lungs, heart, and great vessels?

A

A

Computed Tomography (CT)

54
Q

Iodine-containing contrast material is sometimes used in CT scanning. Patients with a history of allergy to iodine or contrast materials should notify their physicians and radiology staff. True or false?

A

True.
