Ch 5 terms/abbreviation Flashcards
measures the force exerted by blood against vessel walls
blood pressure
blood is under a lot of pressure and gives the highest reading
happens during systole
top # of BP
blood is under little pressure and gives the lowest reading
happens during diastole
bottom # of BP
characteristics of the blood/blood vessels that may affect blood pressure
-elasticity of arteries
-diameter of blood vessels
-viscosity of the blood
-amount of resistance to blood flow
the surge of blood caused by the heart contraction
pulse
= to heart rate
commonly measured at throat or wrist
ACE inhibitor drugs
produce vasodilation to decrease BP
i.e lotensin, capoten
antiarrhythmic
reduces or prevents cardiac arrhythmias
i.e tambocor, corvert
anticoagulant
prevent blood clot
i.e warfarin, coumadin
antilipidemic
reduces blood cholesterol
i.e lipitor, zocor
antiplatelet agents
inhibit ability of platelets to clump together in a blood clot
ie plavix, ticlid
beta blocker drugs
lower heart rate to treat HTN and angina pectoris
i.e lopressor, inderal
calcium channel blocker drugs
decreases force of heart beat to treat hypertension, angina pectoris, and congestive heart failure
i.e cardizem, procardia
cardiotonic
increases force of heart contraction to treat congestive heart failure
i.e lanoxin
diuretic
increases urine production to reduce plasma volume to lower BP
i.e lasix
thrombolytic
dissolves existing blood clot
i.e tPA, activase
vasodilator
relaxes smooth muscle in wall of blood vessel to reduce blood pressure and increase blood flow to ischemic area
i.e nitro-dur, apresoline
vasopressor
contracts smooth muscle in wall of blood vessel to raise BP
i.e vasostrict
AED
automated external defibrillator
AF
atrial fibrillation
AMI
acute myocardial infarction
AS
arteriosclerosis
ASD
atrial septal defect
ASHD
arteriosclerotic heart disease
AV, A-V
atrioventricular
BBB
bundle branch block
BP
blood pressure
