Annotated Study Guide for Cardiac Murmurs

Instructions

Each of the cardiac topics you are responsible for knowing have been collected in the readings for the module and study guide. To help recall and master this material, you will annotate each topic in this study guide with notes, thoughts, and/or images as you perform the required readings at the start of this week. There will be prompts, but do not consider yourself constrained by these, as long as each topic is annotated in some way.

Cardiac Murmurs

Timing

  • Heard longer than heart sounds
  • Palpate the carotid arterial pulse
  • Systolic, diastolic, or continuous

Intensity of Sound

  • Crescendo grows louder, decrescendo gets softer, crescendo-decrescendo, plateau

Location

  • Where does the sound originate from?
  • Listen to all areas- aortic, pulmonic, tricuspid, mitral

Radiation

  • Where does the sound radiate to?
  • Think about direction of the blood flow

Intensity

  • Graded from I to VI
  • Grade I – very faint
  • Grade II- faint but heart immediately, louder than grade II
  • Grade III- Moderately loud
  • Grade IV- loud, thrill
  • Grade V- heard with stethoscope partly off chest, thrill
  • Grace VI- heard with stethoscope off chest, thrill
  • Loud murmurs can have a thrill

Pitch

  • What does it sound like- high, medium, low

Quality

  • Musical, blowing, harsh, clicking, blowing

Position & Maneuvers

  • Is there a change with position- sitting
  • Is there a change with respiration
  • Valsalva or standing will decrease murmurs except for hypertrophic cardiomyopathy & mitral valve prolapse

Extra Sounds

  • S3 is associated with CHF
  • S4 is associated with LVH

Systolic Murmurs

  • Mitral regurgitation, aortic stenosis
  • Benign murmurs

Mitral Regurgitation

Aortic Stenosis

  • Heard at 2nd ICS right side of the sternum
  • Radiates to neck
  • Harsh & noisy murmur
  • Mid-systolic ejection murmur

Diastolic Murmurs

  • Mitral stenosis, aortic regurgitation
  • Diastolic murmurs are abnormal

Mitral Stenosis

  • Heard at the apex
  • Low pitch rumbling murmur
  • Opening snap
  • Little radiation
  • Can be caused by rheumatic heart disease

Aortic Regurgitation

  • Heard at 2nd ICS right of sternum
  • High pitched blowing murmur, decrescendo

Mitral Valve Prolapse

  • S2 click followed by a systolic murmur
  • Loud & musical
  • May be at higher risk for embolism, TIA, AF
  • Diagnosed with echo & Doppler

Continuous Murmurs

  • Begin during systole and continue into diastole
  • Pericardial friction rub- scratching / scraping
  • Patent Ductus Arteriosis (PDA)- machinery like, harsh
  • Mammary souffle- heard during late 3rd trimester / lactation
  • Where will you expect to hear mitral valve prolapse?
  • Describe the sounds of aortic stenosis.
  • Name 2 diastolic murmurs.
  • What is the most common murmur?
  • What is the expected location to hear mitral regurgitation?

Matching

Match the intensity of the murmur to the Grade

Head with stethoscope not touching chest, thrill present                               Grade II

Loud, accompanied by a thrill                                                                        Grade VI

Very faint, not heard if the person changes position                                      Grade I

Usually readily heard, slightly louder, heard in all positions                         Grade III

Loud but not accompanied by a thrill                                                            Grade IV

Can be heard with stethoscope barely on chest, thrill present                       Grade V
