Heart Sounds and Murmurs (incomplete, important info) Flashcards
ejection click what + cause
early systolic. opening of aortic and pulm valves.
ejection click shows what
aortic or pulm stenosis OR pulm trunk or aorta distension
non-ejection click what + cause (mid - late systole)
mitral or tricuspid valve prolapse
diastolic heart sounds
Opening snap, pericardial knock, S3 and S4
Opening snap when and cause
bit after S2. early diastolic. from STENOTIC mitral and tricuspid opening.
opening snap shows what
rheumatic fever. ex. untreated strep throat when younger
S3 best way to hear
bell (LOW PITCHED), cardiac apex if left sided, left lateral decubitus
S3 corresponds to what
rapid ventricle filling
S3 in older people sign of what
dilated ventricle, heart failure, bad ventricle contraction. ex. pushing against high BP
pathologic S3 sometimes referred to as _______
ventricular gallop
S4 best way to hear it
bell (LOW PITCHED), cardiac apex if left sided, left lateral decubitus
S4 cause
stiff ventricle. (hypertrophy or myocardial ischemia)
S4 sometimes referred to as ____
atrial gallop
quadruple beat vs summation gallop
both in patient with both S3 and S4. becomes summation gallop when tachycardia (S3 and S4 fuse. long dull mid diast sound)
pericardial knock heard when, cause and shows what
early diastole, high pitched, caused by stiff pericardium and abrupt cessation of vent. filling, shows pericarditis
heart sounds order if have all
S1, ejection click, non ejection click, S2, opening snap, S3, pericardial knock, S4
7 things to describe murmur
timing, intensity, pitch, shape, location, radiation, response to maneuvers
how to know murmur timing
sense pulse at same time and listen to when appears
murmur intensity how to express it
grading on 6 (systolic) or 4 (diastolic). heard easily at 3.
thrill def and at what murmur intensity
palpable buzzing or vibration (at grade 4)
murmur pitch reflects what
high pitch: high P gradient (blood coming from high P chamber as in aortic stenosis. comes from LV)
low pitch: low P gradient (ex. mitral stenosis)
murmur location def
where best heard
how to describe murmur location
auscultatory area (one of 4)
4 auscultatory areas
aortic area: 2nd intercostal space right to sternum
pulmonic area: 2nd intercostal space left to sternum
tricuspid area: lower left sternal border
mitral area: cardiac apex
