Harvey Lab, stasio Flashcards
Where is S1 loudest? S2?
S1- apex
S2- base
how does inspiration cause split S2
increased blood volume in R ventricle
S3 is best heard where
apex with patient lying no the L side
blood hitting non-compliant ventricle
what causes the S4 sound
vibrations of L ventricle, mitral valve and L ventricular outlow as result of atrial contraction
Waht is best position to hear S4
L lateral decubitus at apex
17 y.o has S2 split and an S3 heart sound. rest of exam unremarkable.. should you be worried?
children and young adults have physiologic filling sounds (S3)
48 y.o obese man with HTN, HLD, has S4 at mitral post, and left carotid bruit. reason for murmur?
ASHD, noncompliant ventricle.
56 y.o with crushing chest pain, dyspnea and diaphoresis. Hx ASHD and angina
dec carotid and peripheral pulses, inspiratory crackles or rales b/l
S3 and S4 present
Dx?
anterior wall MI, S3 indicating significant LV dysfunction
crackles in lungs reflecting acute pulmonary congestion
When is an aortic ejection click heard
onset of LV ejection
When is a pulmonic ejection click heard
onset of RV ejection
When do you hear a mid systolic click? where do you hear it?
mitral valve prolapse
heard at apex in mid or late systole
What are the sounds from pericarditis
triphasic scratchy, grating, rasping or squeking
causes of pericarditis
infectious, MI, cardiac surgery, uremia, metastatic Ca, TB
38 y/o male had recent upper viral infection, leaning forward relieves chest pain
pleural rub with inspiration, normal vesicular breath sounds
has 3 component pericardial firciton rub early and late diastole and mid systolic
acute viral pericarditis
how do you describe a heart murmur
timing, location, radiation, shape, intensity, pitch, quality
