S1
S2 S3 S4 |
S1: AV close
S2: Semilinar close S3: Initial vent filling S4: atrial Kick |
|
on what side of the heart is the cardiac cycle a bit slower?
|
right
|
|
Name three changes that occur in the heart after birth
|
1. Ductus arteriosus and foramen ovale close
2. R heart takes over pulm circut 3. L vent takes systemic circulation |
|
what cardiovascular changes occur in pregnancy
|
add the placenta so
1. overall resistance decreases 2. BV increases 3. BP should decrease |
|
what changes in the heart are seen in older folks?
|
1. heart size decreases
2. left vent hypertrophy 3. valves fibrise and calcify 4. endocardium thickens 5. myocardium becomes less elastic |
|
Dx of orthostatic hypotension
|
Must have 1 of the following:
1, 20 mm drop in systolic 2. 10 mm drop in diastolic 3. cerebral hypofrofusion **sympt must be seen within 2 to 5 min of standing |
|
where is PMI of heart
|
left sternal border
apex 5th intercostal space MCL shouldnt be more than 2.5 cm |
|
what happens to PMI with L vent enlargement
|
it is lateral to MCL
larger than 2.5 cm |
|
whats a thrill
|
palpable mummur (murmmur, you can HEAR it)
**can be due to turbulent flow through any narrowed opening. valvular stenosis, vent septal defect |
|
whats a lift of heave
|
when cardiac impulse can be felt (its NOT heard, NOT a murmmur)
**can be caused by vent hypertrophy or hyperdynamic vent activity |
|
what is the diff btwn a thrill and a lift or heave
|
thrill: hear and feel, palpable murmur
Lift/Heave: cardiac impulse is felt (more vigirous) but NOT heard |
|
what part of stethascope is used for low pitch sounds, high pitch
|
low: bell
high: diaphragm |
|
what happens to PMI for preggers or fatso
|
shifts up and lateral
|
|
where shpuld you listen to hear:
S1 S2 |
S1: AV close (take medicine), best heard at APEX (bottom)
S2: semilunar close, best heard at base |
|
when is there non path splitting of S2
|
inspiration
*physiological, inspiration will delay closure of pulmonic valve |
|
when is there pathological splitting of S2
|
Pulmonic valve may close later due to...
1. atrial septal defect (fixed) 2. pulmonic stenosis (wide) 3. R vent heart failure (fixed) 4. r bundle block (wide) |
|
what is wide slpitting of S2
|
delayed closeure of pulmonic
due to RBBB or Pulm stenosis |
|
what is fixed splittin of S2
|
doesnt vary with inspiration
atria septal defevt r vent failure |
|
what arhythemia is a gallop?
|
S3 present, low pitch, heard with bell at apex, when initial filling of vent is heard. decreased compliance of vent
S1+S2+S3 gallop |
|
what happens to babies at birth
|
they breath, this will decrease pressure in R heart and increase Pressure in L heart, foramen ovale closes, ductus arteriosus closes and the R heart sends things to lungs
|
|
what are some characteristics of babies that clue you in they may have heart failure
|
1. tire when eating
2. breathing changes 3. cyanosis 4. weight gain (go by their smooth curve, not the percents) 5. knee chest position (increase venous return) 6. Moms health during preggo |
|
what does the body do when you stand up fast and blood pools in lower extremities
|
1. decreased venous return, decrease CO, decrease BP
2. baroreceptors will see this and send SNS to increase RESISTANCE, increase venous return, increase CO **this NORMAL response causes: SP to fall 5-10 DP to raise 5-10 increase in pulse 10-25 |
|
what is an S3 look like
what does an S4 look like |
S1 S2 S3 S1
S4 S1 S2 S4 S1 S2 |
|
what pathology elicits S3
|
Kids: usually no biggie
Adults over 40: heart failure, anemia, volume overload, decreased contractility |
|
what pathloogy elicits S4
|
uncommon: heard bc of resistnace to filling/decreased compliance
In traind athletes may be present, no heart disease |
|
is it ok for a babe to have a mummur
|
yep, after 48 hours the holes should all close up and no mummur should be heard
|
|
Children with heart disease will present with...
|
1. weight gain/loss
2. development delays 3. cyanosis 4. clubbing of fingers/toes |
|
NSR
Brady Tachy |
60-100
<60 >100 |
|
what is a systolic mummur
what is a diastolic mummur |
S1 shh S2
S1 S2 shh |

systolic mumur occurs after what heart sound, diatsolit
|
systolic: S1
Diastolic: S2 |
|
how are mummurs graded
|
severity out of 6
1/6 5/6 etc |

|
3/6 moderatly loud
