What does the cardiovascular system (CVS) consist of?
heart, blood vessels (arteries, veins, and capillaries)
-
Structure
interior (atria and ventricles, septum, valves), walls (myocardium, pericardium, etc.)
-
Conduction
- Has own O system, would continue beating outside of body, nodes and bundles and fibers oh my!
- SA node-pacemaker sends to AV node
-
Circulation: arteries, veins, and capillaries
- Arteries: thick, muscular, and elastic for surge of blood, can feel pulses at arteries
- Veins: less elastic and muscular, blood pressure too low to push blood on own, get help (where valves leak are varicose veins)
- Capillaries: very tiny, very thin walls, only one cell thick, embedded in organs, feed walls of arteries and veins
-
constricto
to draw together
-
-
angio AND vasculo AND vaso
vessel
-
-
-
athero
faty debris; fatty plaque
-
-
-
-
phlebo
vein (phlebotomist- take blood)
-
-
-
-
-
Pulses:
- temporal (head)
- radial (wrist)
- femoral (groin)
- carotid (neck)
- brachial (elbow)
- popliteal (behind knee)
- dorsalis pedis (top of foot)
-
-
CAD
coronary artery disease
-
-
CHF, what's the appropriate term?
congestive heart failure, now just HF
-
CPR
cardiopulmonary resucitation
-
CABG
coronary artery bypass graft-- # corresponds to how many veins grafted
-
AAA
abdominal aortic aneurysm: damage done to distal body part
-
-
MI/STEMI
- myodcardial infarction= acute coronary syndrome
- if it's ischemic than STEMI: ST elevated myocardial infarction
- if not ischemic, than NST angina
-
TIA
transient ischemic attack-- ministroke
-
PCI
percutaneous cardiac intervention
-
Echocardiogram gives what?
ejection fraction
-
Process of plaque and 90 minute window
Plaque closes off vessel to heart or break off and travel, gets clogged, O closed off--go in with endovascular into coronary arteries, place stint to allow blood flow-- we have 90 min to return O to ischemic muscle--otherwise stunning will turn to death
