Cardiac (Exam #1) Flashcards
(283 cards)
Which diagnostic test is used to detect electrical activity?
EKG (electrocardiography)
Which diagnostic test is used to evaluate acute chest pain or acute palpitations?
EKG (electrocardiography)
What is continuous EKG monitoring in an inpatient setting?
Telemetry
What is the primary/preferred biomarker of cardiac injury (lab test), and when is it used?
Troponin
- Diagnose/prognose acute MI
Besides Troponin, what two cardiac enzymes are used to evaluate cardiac injury?
- Creatine Kinase (CK)
- Creatine Kinase Myocardial Band (CK-MB)
Which diagnostic test is the primary modality for evaluation of cardiac anatomy and function?
Echocardiography
What is US machine transmits sound pulses into tissue using crystal probe → sounds wave travels and hits tissue → some sound waves reflected back to probe → waves picked up by probe, relayed to machine/2D image made?
Echocardiography
Is TTE or TEE Echocardiography preferred?
TTE
Which diagnostic test is used to evaluate wall motion during/after MI, calculate EF/systolic function, evaluate valve structure/function?
TTE Echocardiography
Which diagnostic test is used to detect clots, valvular pathology (endocarditis), septal defects/patent foramen ovale?
TEE Echocardiography
Which diagnostic test measures the heart’s ability to respond to external stress in controlled environment?
Cardiac Stress Tests (EKG Stress Test, Nuclear Stress Test, Stress Echocardiogram)
Which diagnostic test is used to evaluate exertional chest pain, CHD with new/worse symptoms, newly diagnosed CHF/cardiomyopathy?
Cardiac Stress Tests (EKG Stress Test, Nuclear Stress Test, Stress Echocardiogram)
Which two diagnostic tests have high sensitivity, can localizes ischemia, have more information on cardiac structure/function and are good pre-op evaluation?
- Nuclear Stress Test
- Stress Echocardiogram
Which of the cardiac stress tests prefers exercise stress to pharmacologic stress? Which two use pharmacologic?
EKG stress test = exercise
Nuclear Stress Test, Stress Echocardiogram = pharmacologic
Which diagnostic test involves rest EKG → exercise to target HR/symptoms/time limit → EKG/symptoms taken during exercise?
EKG stress test
Which diagnostic test involves Technetium-99 administered IV → waiting period to allow radioactive tracer distribution → gamma-ray scan at rest → stress induced via exercise/pharm → target HR/symptoms achieved, and another radiotracer injected IV → second waiting period → second gamma-ray scan obtained → two images compared?
Nuclear Stress Test
Which diagnostic test involves TTE at rest → stress induced via exercise/pharm → target HR/symptoms achieved → stress echo images obtained → two images compared?
Stress Echocardiogram
Which diagnostic test requires the use of vasodilators (Adenosine, Dipyridamole) or ionotropes (Dobutamine)?
Nuclear Stress Test
Which diagnostic test is indicated if abnormal resting EKG, assess areas of myocardial ischemia, determine location/size of injured muscle after MI?
Nuclear Stress Test
Which diagnostic test is indicated if known/suspected CAD, evaluate CP, SOB, exertional dyspnea, evaluate valvular abnormalities?
Stress Echocardiogram
What medication is preferred when performing a Stress Echocardiogram?
Dobutamine
Which diagnostic test involves continuous ambulatory electrocardiography over 1-2 days + symptom diary?
Holter Monitor
Which diagnostic test is indicated if DAILY palpitations, syncope?
Holter Monitor
Which diagnostic test involves NON-continuous ambulatory electrocardiography over 30-60 days + symptom diary?
Event Monitor
