🫀HEART SOUNDS MADE SIMPLE

🫀HEART SOUNDS
🫀The heart's job is to pump blood and this can create some noise.
🩸1st sound (S1): "LUB". This sound is due to the closure of the AV Valves (bicuspid/tricuspid). It happens when the ventricles start to contract "Systole".
🩸2nd sound (S2): "DUB". This sound is due to the closure of the SL Valves (aortic/pulmonic). It happens when the ventricles start to relax "Diastole".
✅S1 + S2 = normal heart sounds✅
🩸3rd sound (S3): caused by increased atrial pressure leads to rapid ventricular filling.
👤Found in: HEART FAILURE with older patients, normal in younger patients less than 40 yrs.
🎶Sound: KEN...tucky, KEN...tucky. Very similar to the sound of a horse competing in the KENTUCKY derby.
🩸4th sound (S4): caused by a forceful atria contraction against noncomplaint/stiff ventricle.
👤Found in: Patients with stiff ventricles from hypertension, aortic stenosis, ischemic heart disease.
🎶Sound: teNNE..ssee, teNNE..ssee
HEART MURMUR: normal blood flow is smooth with ⬇️ noise, heart murmurs are turbulent with ⬆️ noise.
🩸Mumur of Mitral Stenosis: caused by mitral valve narrowed.
👤Found in: Rheumatic Heart Disease, Infective Endocarditis
🎶Sound: whispering the letter "R"
🩸Murmur of Mitral Regurgitation: caused by incompetent mitral valve.
👤Found in: Weak Valve, Ischemic Heart Disease, Infective Endocarditis, Rheumatic Heart Disease
🎶Sound: Being freezing and saying "Brrrr" 🥶❄️
🩸Murmur of Aortic Stenosis: narrowed aortic valve.
👤Found in: idiopathic age related calcification of valve
🎶Sound: Touching lips to a fuzzy microphone.🎤
🩸Murmur of Aortic Regurgitation: caused by incompetent aortic valve that causes backflow of blood.
👤Found in: Connective Tissue Disorders (ex: Marfan Syndrome)
🎶Sound: diving and hearing noise underwater 🤿💦
Hope this helps!
