60 year old female with history of obesity and DM II. is experiencing a heart attack
anatomy of the heart
muscular organ
size of your fist
pumps blood
carries deoxygenated blood to the lungs
has a parietal and vesceral pericardium
the heart has 4 chambers
right and left atrium
right and left ventricular
superior vena cava
inferior vena cava
aorta
pulmonary artery
pulmonary veins
tricuspid valve
bicuspid vavle
pathway of blood
superior vena cava
inferior vena cava
coronary sinus
right atrium
tricups valve
right ventricule
pulmonary semilunar valve
pulmonry truck
right and left pulmonary artery
into lungs pick up oxygen
left atrium
biicuspid valve
left vetricle
aortic semilunar valve
aorta
systemic system
papillary muscles
project into ventricular cavity
anchors
atrioventricular vavles
prevents back flow into atria
tricuspid valve
made up of 3 cusp
mitral vavle
made up with two cusp
sounds of the heart
first sound
ventricular systole
closing of the AV valves
ventricular diastole
closing of the SL valves
lub-dub sound
systole
heart contraction
diastole
heart relaxation
normal blood pressure 120/80
heart beats 75 per min
tachycadia
fast heart rate
more than 100 beats
bradycardia
slow heart rate
less than 60 beats
stroke volume
amount of blood pumped out of one ventricle
normal SV
120ml-50ml=70ml/beat
who can effect
preload
contractillity
afterload
degree of stretch of heart muscle
just before a contraction
strength of contraction
based on calcium levels
pressure that ventricules overcome to eject blood
cardiac out put
increase output above rest level
HR increases and SV
during exercise
amount of blood pumped out by each ventricule
has a long history of DM II and has obesity
failed mitral valve
does not close all the way
leave untreated
causes heart failure
heart arrhythmias
future effects
blood clots
hypertension
stroke
shortness of breath
circulatory effects
hard to breath
lungs cant get oxygen
which the heart can not flow right
