Dx Testing Flashcards
Provides information for the diagnosis and management of episodes of arrhythmias and symptoms
Holter monitor
Continuous 24 hour ECG
What are the indications for a Holter monitor
- Identifying Symptoms associated with dysrrhythmias
- Describe dysrhythmias noted with activity
- Evaluate anti-arhythmia therapy
- Observe Pacemaker Fx.
Indicated to investigate the cause, location of origin, and best treatment for various abnormal heart rhythms
Electrophysiology Study (EPS)
Noninvasive procedure that evaluates the functioning heart.
Echocardiography
•Allows for improved visualization of cardiac structures and function and is valuable in the intraoperative and perioperative monitoring of left vent. Performance
Transesophageal Echo
TEE
What is most common evaluator of Cardioembolic stroke?
Transesophogeal echo
Evaluates ischemia-induced wall motion abnormalities
Streess echo
Contrast echos have improved Dx accuracy to assess
Myocardial perfusion and Ventricular Chambers
Imaging techniques used for evaluation of CAD and cardiac dysfunction
SPECT PET CT EBCT MUGA MRI
Noninvasive method to detect and quantify myocardial perfusion defects and contractility defects and is used with radioactive isotopes
Singe-photon emiission Computed tomography
Provides visualization and direct measurement of metabolic functioning including glucose and fatty acid metabolism and blood flow of the heart
PET scan
Positron emission tomography
What is gold sttandard for Blood flow measurement and metabolic assessment of hearT?
PET scan
Used to identify masses in cardiovascular system (Aneurysm, thickening)
Computed tomography
2 types of CT
CT angiography
Spiral CT
Which CT scan highlights coronary arteries to eval for CHD?
CT angiography
Which CT is used to evaluate presence of Pulmonary embolism?
Spiral CT
What imaging detects and quantifies coronary athereosclerosis by detecting coronary Calcification?
Electron beam computerized tomography (EBCT)
What imaging calculates LV ejection fraction?
MUGA (multi-gated aquisition imaging)
Imaging that evaluates morphology, cardiac Blood flow, and myocardial contractility
MRI
Imaging used to assess coronary perfusion with agents such as Thallium-201 and technetium-99m
Radioactive nuclide perfusion imaging
When are agents from radioactive nuclide prefusion imaging injected? And what does dead myocardium appear as?
Following exercise/ stress test
Appears as cold spot.
Cold spots in RNPI immediately after and 4 hours after considered ___
Reperfusion after 4 hours is
Irreversible damage
Ischemic
Which radioactive nuclide agent is more stable?
Sestamibi
A physiologic stress test while pt is at rest?
Pharmacologic stress testing.
Common agents for pharmacologic stress test
Dupyridamole
Dobutamine
Adensoine
Invasive procedure
Establishes or confirms a diagnosis of cardiac dysfunction or heart disease, demonstrates the severity of coronary artery disease or valvular dysfunction
Cardiac catheterization
What determinations are made from Cardiact catheterization?
Presence of CAD
Presence of LV dysfunction/ aneurysm
Presence of valvular heart disease
Pericardial disease
Cardiac catheterization used as treatment
Percutaneous coronary intervention PCI
When does pressure need to be placed after cardiac catheterization/
4-8 hours
Diagnostic test for Coronary Spasm
Ergonovine Stimulation
Needed for eval and mangement of congenital Pulm anomalies
Bronchography
Indicated to assess for infection of bronchioles
Bronchoscopy
