Give this one a try later!
left anterior descending (coronary artery)
Moderate concussion
Give this one a try later!
GCS 8-13
LOC >30 minutes
Amnesia >24 hours
May display decerebrate or decorticate posturing
,Digitalis
Give this one a try later!
-Blocks the Na/K pump, which increases intracellular Na, decreases activity
of the Na/Ca exchanger, and increases intracellular Ca
-Strengthens the contraction of the heart
Autonomic Dysreflexia
Give this one a try later!
(potentially life threatening emergency!) HOB elevate 90 degrees, loosen
constrictive clothing, assess for full bladder or bowel impaction, (trigger)
administer antihypertensives (may cause stroke, MI, seizure)
T7 and above injury is at risk. Noxious stimulus below the level of injury,
manifestations will be different above and below level of injury
Catecholamines
Give this one a try later!
Increase rate of depolarization
Increases heart rate
Preload/Afterload
Give this one a try later!
, Preload is dependent on the amount of blood going returning to the right
ventricle, and the amount of blood left in the left ventricle at the end of
systole. Afterload is the systemic resistance that the ventricle pushes
against to contract after leaving the heart.
aortic valve stenosis
Give this one a try later!
Narrowing of the aortic valve
Can be caused by rheumatic endocarditis
<1 cm
Right ventricle systolic pressure
Give this one a try later!
15-28 mmHg
Atrial (SA/AV node) action potential
