What is a non-invasive assessment?
An observation indicating an impairment of cardiac function is decreased level of consciousness
How does Mucus Membrane Color help with assessment?
The color is a reflection of hemoglobin saturation in the capillary blood
If Cardiac function is ______, pulse will be affected.
What is "Auscultation of Heart Sounds?"
Auditory examination of the heart.
- Done with a stethoscope over the valve, chamber or great vessel
What can Vectocardiogram assist in finding?
1) precisely locate the site of myocardial infarction
2) diagnose conduction defects
3) diagnose chamber hypotrophy
On a vectocardiogram, where are they placed?
fiver over the pericardium
one on the left leg
one in the back of neck
What is Pulse Tracing?
Pulsation described by the flow of blood through the artery during CC
can be drawn as a waveform potting pressure against time
What is an Echocardiogram?
ultrasonic sound waves that generate and direct into the cardiac structures and reflect waves at different angles and lengths according to structure and density
What is a Doppler Study?
Made by using a handheld microscope placed on the skin over a lubricating gel
What does a Chest X-ray show?
examination of the size and contour of the heart and related structures are visualized
What is an invasive assessment of function?
Greater risk of the individual study
X-ray with barium shows a cardiac silhouette shows a enhanced image than a single chest x-ray alone.
For a right-heart cath, the cath is placed in the _____ or _____ artery
Brachial or Femoral
For a left-heart cath, the cath is commonly placed in the ____ artery
Once the cath is placed and guided into the atrium:
- pressures are recorded
- blood samples are obtained to examine oxygen content
- contrast medium is injected to visualized chamber function and valve patency
Once the cath is passed into the ______, the sequence is repeated
What is a Coronary Angiography?
Fluoroscopic visualization of the coronary arteries and left heart structure using an (iodine) contrast dye.
What is another name for Coronary Angiography?
Hot and Cold spot Imaging
Nuclear imaging with radiohead pharmaceuticals:
1) conflicting history for myocardial infarction
2) Equivocal ECG abnormalities
3) an individuals cardiac enzymes have been elevated because of surgery or trauma
What is cyanosis?
Blue or purple coloration of skin of mucous membrane due to low oxygen
Where are 9 of the pulse points?
- Common Carotid
- Posterior Tibial Artery
- Dorsalis Pedis Artery
What is a myxoma?

Used to estimate the ___ _____ through blood vessels by bouncing ____ _____ sound waves off circulating _____.
Fluid is always ____ and tissue is _____
These drugs acts indirectly at the receptor
Adenosine and Dipyridamole
This drug acts as an adenosine A2A receptor which affects the heart more than the lungs
This drug is a beta-agonist
