Chapter 9 Flashcards
what does the right side of the heart do
receives blood from the body and delivers it to the lungs
What does the left side of the heart do
receives blood from the lungs and delivers oxygen rich blood to the body
Tricuspid valve
right atrioventricular valve
mitral valve/ bicuspid
left atrioventricular valve
What is inbetween each ventricle and artery
valve
What is the purpose of valves
to prevent retrograde blood flow (blood from flowing backwards)
pulmonary circulation
flow to and from the lungs; blood from the right side of the heart to the lungs and back to the left atrium
systemic circulation
flow to and from the body; blood from the left of the heart to the body tissues back to the right atrium
arteries
takes blood from the heart
veins
take blood back to the heart
capillaries
connect arteries and veins
valvul/o
valve
atri/o
atrium
sept/o
septum; wall between the left and right side of the heart
ASD
atrial septal defect; hole between atria, genetic
VSD
ventricular septum disorder; hole between the ventricles, genetic
ventricul/o
ventricle
coron/o
heart
coronary artery
artery to the heart muscle
cardi/o
heart
cardiac arrest
heart is not beating
myocarditis
inflammation of the heart muscle
aort/o
artery from left ventricle to system circulation
arteri/o
artery that moves blood from the heart
ather/o
fatty plaque
atherosclerosis
hardening of artery due to fatty and calcium plaque
vena cava
large vein that brings blood from the body to heart
cava
hollow
superior vena cava
blood from above the diaphragm to the heart
inferior vena cava
blood from below the diaphragm to the heart
pectoralgia
pain in the chest; not necessarily due to the heart
pector
chest
angina pectoris
pain in the heart; due to irregular flow to the heart
palpitation
rapid or irregular heartbeat
arrhythmia/dysrhythmia
irregular heartbeat
hemorrhage
loss of blood
what are the indicators of poor perfusion
blue and pale skin
what is the use of the pulse with the HR
used to measure HR and how strong the flow is
ECG/EKG
electrocardiogram; record of electrical activity
ECHO
echocardiogram; ultrasound of the heart to see the heart functioning (valves opening and closing and blood flow)
occlusion
cutoff in blood flow
ectasia
dilation of a vessel
What is a sequelae of a high BP
cardiomegaly due to the myocardium having to work harder due to overcome greater pressure
murmur
abnormal heart sound
cyanosis
blue skin
aortectasia
widening of the aorta
aortic dissection
wall splitting due to blood getting between layers through an ulcer
varicose veins
enlarged, dilated veins in surface veins
varicose
swollen
venostasis
trapping of blood in extremities; due to pressure on a nerve
vascular endoscopy
process for viewing inside a blood vessel
sonography
ultrasound waves to view something
transesophageal echocardiogram
sonogram from a device inserted into the esophagus
stress electrocardiogram
ECG during a stress test
what is normal BP
120/80 (systolic, diastolic)
hypertension
higher than 130/80
hypotension
lower than 90/60
aneurysm
weakened area that bulges
aortic regurgitation
backflow of blood, due to a weak heart valve
thrombophlebitis
inflammation of the vein due to a clot
endocarditis
inflammation of the inner lining of the heart
myocarditis
heart muscle inflammation
pericarditis
inflammation of the outer lining of the heart
valvulitis
inflammation of the valves of the heart
congestive cardiomyopathy/ dilated cardiomyopathy
heart can’t pump out most of the blood causing it to stretch and dilate with a low ejection fraction
ejection fraction
amount of blood pumped out over total amount of blood in a ventricle
What is the normal ejection fraction percentage
50-75%
what is low ejection fraction percentage
36-49%
what is a seriously low ejection fraction percentage
less than 36%
hypertrophic cardiomyopathy
enlarged heart muscle obstructing flow
restrictive cardiomyopathy
stiffened heart muscle restricts filling, therefore less blood is pumped
coronary thrombosis
clot in a coronary artery
myocardial ischemia
reduced blood to the heart due to a blockage of blood to the heart muscle
MI
myocardial infarction; death of some heart tissue
cardiopulmonary bypass
device to act as the lungs during surgery on the heart
percutaneous coronary intervention
catheter through the skin and through a large artery to reach the heart for the surgery
percutaneous
through the skin
antianginal
used for chest pain
antiarrhythmic
used for arrhythmias
antihypertensive
for high BP
vasodilator
relaxes or expands the blood vessels; used for high BP
vasopressor
constricts or narrows the blood vessel; for low BP
cardiotonic
increases strength of cardiac muscle
CPR
cardiopulmonary resuscitation
pericardiocentesis
puncture of the pericardium to let out excess fluid
anastomosis
surgical connection of two vessels
NSR
normal sinus rhythm
Afib

CO
cardiac output (blood pumped put per minute)
SV
stroke volume (blood pumped per stroke)
CTA
