Heart Murmurs Flashcards
What are the 3 most important ways to classify heart murmurs? What other ways can they be classified in?
Timing (systolic or diastolic), Location, Intensity (Grade), radiation, pitch, shape.
What type of heart disease would you be thinking if you had a left apex systolic murmur?
Mitral insufficiency
What type of heart disease would you be thinking if you had a left base systolic murmur?
Aortic or pulmonic stenosis
What type of heart disease would you be thinking if you had a right apex systolic murmur?
Ventricular septal defect
What type of heart disease would you be thinking if you had a right base systolic murmur?
Tricuspid insufficiency or aortic stenosis.
What type of heart disease would you be thinking if you had a left apex diastolic murmur?
Mitral stenosis
What type of heart disease would you be thinking if you had a left base diastolic murmur?
Aortic or pulmonic insufficiency
What type of heart disease would you be thinking if you had a right base diastolic murmur?
Aortic insufficiency or tricuspid stenosis.
What type of heart disease would you be thinking if you had a continuous murmur?
Potentially PDA
What is a grade I murmur?
Barely audible in ideal conditions.
What is a grade II murmur?
Clearly audible at point of maximum intensity, no radiation.
What is a grade III murmur?
Clearly audible sound as loud as S1 and S2, may radiate.
What is a grade IV murmur?
Louder than S1 and S2.
What is a grade V murmur?
Palpable thrill over point of maximum intensity.
What is a grade VI murmur?
Audible with stethoscope just off chest
What type of murmurs can you get when classified by shape?
Holosystolic/pansystolic (same thing), crescendo-decresendo, diastolic decrescendo, mid-systolic etc.
What is a heart murmur?
A heart sound associated with turbulent blood flow.
How can you differentiate a systolic from a diastolic murmur if you’re struggling when auscultating?
A pulse always happens when you can hear a systolic murmur.
