Heart Murmurs Flashcards
right-sided murmurs increase in intensity during
inspiration
murmurs d/t HCM increase in intensity during which 2 maneuvers?
- Valsalva
2. standing from SQUATTING position
what happens to the click in MVP w/ Valsalva and standing from SQUATTING position?
may move closer to S1
what happens to the murmur in MVP w/ Valsalva and standing from SQUATTING position?
murmur lengthens
what helps DIFFERENTIATE HEART MURMURS?
ABNORMAL SPLITTING OF S2
split S2 normally heard when?
inspiration
splitting of S2 during inspiration AND expiration occurs when?
conditions causing delay in RV ejection
what conditions cause RV ejection delay?
splitting during inspiration and expiration
- RBBB
- pulmonary valve stenosis
- VSD w/ LEFT-to-right shunt
- ASD w/ LEFT-to-right shunt
what conditions cause prolong LV ejection?
reversed or expiratory splitting
- LBBB
- AS
- HCM
- ACS w/ LV dysfunction
innocent heart murmurs have what characteristics?
- midsystolic
- located at base of heart
- grade 1/6 to 2/6 w/o radiation
- a/w normal S2 splitting
characteristics of murmurs indicating SERIOUS cardiac dz
- S4
- murmur grade 3/6 or more
- ANY diastolic murmur
- continuous murmurs
- abnormal S2 splitting
DON’T BE TRICKED
what heart sounds/murmurs are normal during pregnancy?
- increased P2
- S3
- early peaking systolic murmur over ULSB
DON’T BE TRICKED
do innocent heart murmurs require echocardiographic confirmation?
NO
