how does the heart get the blood that coronary arteries
keeps it alive?
path of blood flow through the heart inferior/superior vena cava
right atrium
tricuspid valve
right ventricle
pulmonic valve
pulmonic artery
lungs (gas exchange happens here)
pulmonary veins
left atrium
mitral/ bicuspid valve
left ventricle
aortic valve
aorta to rest of body
"electrical" conduction of the heart SA node
AV node
bundle of his
right and left bundle branches
purkinji fibers
communication between arteries and arteries-arterioles-capillaries-venule-veins
veins
exception of arteries caring pulmonary artery caries deoxygenated blood
oxygenated blood
,exception of veins carrying pulmonary vein carries oxygenated blood
deoxygenated blood
air sacs that are surrounded by alveoli
microscopic capillaries to "restock"
blood with O2
pulmonary circulation the flow of blood as it returns back to the heart and
goes to the lungs to pick up O2, then goes back to
the heart
Systemic circulation blood going through the body. leaves through aorta
and returns through the vena cava
invasive sterile procedure used to cardiac cath
visualize the heart's chambers, valves,
great vessels. and coronary arteries
areas of insertion for a cardiac cath femoral or radial artery
two diagnostic tests that can measure cardiac cath and echocardiogram
ejection fraction
after a cardiac cath that was accessed pt lies supine (6-8 hrs) with a sand bag over a
through femoral artery pressure dressing to prevent hemorrage
what do monitor after femoral or peripheral pulses distal to site, VS and complaints of
radial accessed cardiac cath numbness or tingling
Graphic study of electrical activities of electrocardiogram (ECG, EKG)
heart muscle
12 lead EKG has how many leads 10 leads
placement of leads for a 12 lead EKG 6 on chest, 4 on limbs
P wave on EKG represents depolarization (contraction) of atrial
, QRS wave on EKG represents depolarization (contraction) of ventricles
T wave on EKG represents repolarization (relaxation) of ventricles
cardiac monitor continually monitors a pts cardiac electrical activity
and displays it to a video screen (telemetry)
what are cardiac monitors used for monitor a pts condition in case there is a sudden
change or to detect abnormalities
cases in which a cardiac monitor hx of cardiac disease
could be used angina pectoris (chest pain)
suspected dysrhythmias
change in meds
surgery
electrolyte abnormality or unexplained syncope
how many electrodes are used for 5
cardiac monitor
nursing interventions for cardiac make sure electrodes seal to skin well
monitors change them often
keep check on leads and batteries
exercise by a pt to evaluate how heart exercise/stress ECG
responds to physical exertion
what does stress ECG evaluate? ischemia, dysrhythmias, extent of cardiac capability
under extreme circumstances
uses high frequency ultrasound echocardiogram
directed at the heart
what can an echo see size, shape, and position of cardiac structures
detects valve problems and cardiac output and
ejection fraction
what is ejection fraction? cardiac output of the ventricles
