2410<3assess (exam1) Flashcards
the __ is the area on the anterior chest that overlies the great vessel
prechordium
the __occupies most of the anterior cardiac surface
(R) ventricle
the __ of the heart refers to the proximal surface of the heart at the right & left 2nd ICS close to sternum
base
the __forms the left lateral margin of the heart
(L) ventricle
its tapered tip is referred to as the__ and produces the apical impulse AKA point of maximal intensity
apex
the __ & __ return o2 poor venous blood to the (R) side of <3
superior & inferior vena cava
the blood flows through the right __ through the __ & into the __
atrium, tricusid valve, (R) ventricle
the __ blood leaves the right ventricle through __ & carries the venous blood to the __
unoxygenated blood, pulmonic valve, pulmonic artery
the __ returns o2 rich blood to the __ through the __ into the __
pulmonic vein, (L) atrium, mitral valve, (L) ventricle
it is delivered to the body through the __ and into the __
aortic valve, aorta
position of <3
extends from 2 ICS to 5 ICS from (R) border of the sternum to LMCL
describe position of: cardiac valves tricuspid mitral aortic pulmonic
separates RA from RV
separates LA from LV
btw LV & aorta
btw RV & pulmonary artery
describe diastole
- valve
- pressure
- 1st & last phase
- end
- associated sound
ventricular relax
- AV valves are open
- atrial pressure > ventricular pressure
- 1st: early/protodiastolic filling
last: atrial systole or presystole (atrial kick) - end: atria contract pushing remainder of blood into ventricles
- normally silent
describe systole
- valve
- pressure
- 2 phases
ventricular contract
- (AV) mitral & tricuspid valve closed
- ventricular pressure> atrial pressure
- S1 phase S2 phase:
what are AV valves
(atrioventricular) mitral & tricuspid
what are SL valves
(semilunar) aortic & pulmonic
describe two phases of systole where best heard
S1 phase: CLOSURE OF AV valves signal sysole and -pressure in ventricles rise SL (aortic & pulmonic) valves open (heard @ apex)
S2 phase: @ end of systole, ventricular pressure decrease and SL valves close, CLOSURE OF SL valves signals end of systole ( heard @ base)
effects of respiraton on <3 & what is it called
moRe right Less left
decrease in intrathroacic pressure -> increase venous blood on (R) side of delays closure of pulmonic valve
less volume on (L) -> aortic valve closes early
SPLIT S2
Describe S3
- what happens
- when it happens
- valves
- best heard
protodiastolic phase (early diastole)
- rapid filling
- immediately after s2
- AV valves opened-> blood rushing in ventricles
- left lateral position apex
when will you hear S3
- in people with heart failure or high cardiac output state or filling overlaod
- can hear in young ppl w/ compliant vessels
Describe s4
- when
- aka
- whats happening
presystolic phase
- occurs before s1, at end of diastole
- presystole
- ventricles are resistant to filling & atria push blood into noncompliant ventricles
define murmur & conditions that cause it
gentle blowing swishing sound
increase velocity, viscosity in blood
defects in valves
dilated chamber
developmental changes in infants & children
<3 is more horizontal
apex is higher (4th ICS MCL)
adult position by 7 yo
developmental changes in preg. women
blood volume increase by 30-40%
HR increase
BP low due to peripheral vasodilation
developmental changes in aging adult
increase BP
increase HR
arrythmia increase
increase incidence in <3dz
define angina & describe symptoms
chest pain
diaphroresis, pallor, palpitations, dyspnea, nausea, trachy<3
define DOE & PND
Dyspnea on exertion
paroxysmal nocturnal dyspnea (occurs with <3 fail)
what happens in PND
Pt lies down-> increase of volume of intrathoracic blood to weak <3 cant accomodate increase of blood, pt wakes up SOB
define hemoptysis
when is cardiac fatigue the worst
blood in sputum
evening
where are carotids palpated
where are carotids auscultated
base of neck
angle of jaw, mid cervicle, base of neck
why do we inspect JVP
Jugular venous pressure
- can reflect central venous pressure
- no cardiac valves separate the superior vena cava from RA
- JVP gives good info about (R) side of <3
