Cardiovascular - Heart Sounds Flashcards
Dilated cardiomyopathy heart sound?
S3 and S4 in left and right side
Hypertrophic cardiomyopathy heart sounds and murmurs?
Split S2, S4
Harsh systolic ejection (crescendo / decrescendo) along LLSB or apex, best heard during Valsalva when there is increased intrathoracic pressure
Restrictive cardiomyopathy heart sounds?
Normal S1 and S2
S3 (loud early diastolic filling sound) may be present
Identify heart pumping events and associated sounds
Diastole - - Ventricles fill
Systole - - Ventricles Contract
S1 - Mitral and Tricuspid valves closes after diastole completes and ventricles are filled
Ejection - Aortic and Pulmonic valves open - (pulmonic ejection click heard after S1 in Pulmonic Stenosis)
S2 - Aortic and Pulmonic Valves close after systole completes
Opening sound - Diastole opens mitral and tricuspid valves
S3 - Early diastolic filling sound indicating rapid ventricular filling
S4 - Sound of atrial contraction immediately prior to S1
Endocarditis, myocarditis and pericarditis murmurs?
Endocarditis - - Regurgitation murmurs
Myocarditis and Pericarditis - - Pericardial friction rub - grating, rasping, scratching) 3 part rub in systole, early and late diastole
Left sided CHF heart sounds murmurs and lung sounds?
S3 (loud early diastolic filling sound)
Mitral regurgitation murmur also possible
Crackles on lung auscultation
Right sided CHF heart sounds, murmurs and lung sounds?
S3 (loud early diastolic filling sound)
Tricuspid regurgitation murmur
May hear left sided sounds like mitral regurgitation and crackles on lung auscultation
Aortic stenosis murmur? Where is heard?
Crescendo-decrescendo ejection murmur at 2nd right interspace
Musical sound at apex
S3, S4
Aortic stenosis murmur radiates to where?
Murmur radiates to right clavicle and both carotid arteries
Aortic stenosis sound heard at apex?
Musical sound at apex
Aortic stenosis additional heart sounds?
S3 (loud, early diastolic filling) and S4
Mitral stenosis characteristic sound?
Loud opening snap when leaflets of mitral valve open abruptly after S2
Mitral stenosis murmur occurs when?
Diastolic murmur in Mitral Stenosis
Mitral stenosis murmur sounds like what?
Decrescendo low pitch murmur - sound like a rumble
Mitral stenosis murmur increases with what?
Increases after Valsalva and when squatting
