Study Notes

Vital Signs

  • Normal Heart Rate: 60-100 bpm
  • Tachycardia: >100 bpm
  • Bradycardia: <60 bpm
  • Normal blood pressure: Varies based on age, race, and other factors
  • Elevated Jugular Venous Pressure (JVP): > 3 cm (or possibly 4cm) above the sternal angle
  • Elevated JVP can be caused by congestive heart failure (CHF), Pulmonary hypertension, tricuspid stenosis, or pericardial compression/tamponade
  • Decreased JVP can be caused by hypovolemia or loss of blood
  • Carotid Upstroke: Brisk = normal, Delayed = possible aortic stenosis, Bounding = possible aortic insufficiency
  • Auscultate carotid arteries to assess for bruits

The Cardiac Cycle

  • Systole: Ventricles contract, right ventricle pumps blood into pulmonary arteries (pulmonic valve open), Left ventricle pumps blood into the aorta (aortic valve open)
  • Diastole: Ventricles relax, blood flows from the right atrium to the right ventricle (tricuspid valve open), blood flows from the left atrium to the left ventricle (mitral valve open)

Physical Exam - Auscultation

  • Aortic Area: 2nd ICS, right sternal border
  • Pulmonic Area: 2nd ICS, left sternal border
  • Tricuspid Area: 3rd/4th ICS, left sternal border
  • Mitral Area: 5th ICS, left midclavicular line

Cardiac Auscultation

  • Auscultate all listening areas for S1 and S2 using the diaphragm of the stethoscope, then auscultate the apex with the bell
  • Diaphragm is best for high-pitched sounds: S1, S2, S4, most murmurs
  • Bell is best for low-pitched sounds: S3, mitral stenosis

Describing Heart Murmurs

  • Timing: Systolic or diastolic? Palpate carotid upstroke (occurs in systole) while auscultating
  • Duration: Early/mid/late systolic (or holosystolic), Early/mid/late diastolic
  • Shape: Crescendo, decrescendo, or both (“diamond-shaped”)
    • Crescendo-decrescendo systolic murmur: Aortic stenosis
    • Holosystolic murmur: Mitral regurgitation
  • Quality: Harsh, musical, soft, blowing, rumbling
  • Pitch: High, medium, or low pitched
  • Location: Area where best heard

Cardiovascular Examination

  • The examination includes vital signs, neck, chest, abdomen, lower extremities, and special tests.

Vital Signs: Heart Rate and Blood Pressure

  • Normal Heart Rate: 60-100 beats per minute (bpm)
  • Tachycardia: >100 bpm
  • Bradycardia: < 60 bpm
  • Normal blood pressure: < 120/80 mmHg

Neck: Jugular Venous Pressure (JVP)

  • JVP is best assessed with the patient lying at 30-45 degrees
  • Normal JVP: 2 cm or less above the sternal angle
  • Elevated JVP: 3 cm or more above the sternal angle
  • Causes of elevated JVP include: Congestive Heart Failure (CHF), Pulmonary hypertension, tricuspid stenosis, pericardial compression/tamponade.
  • Decreased JVP can occur with hypovolemia and/or blood loss.

Neck: Carotid Arteries

  • Carotid upstroke can be:
    • Brisk - normal
    • Delayed - suggests aortic stenosis
    • Bounding - suggests aortic insufficiency
  • Auscultate the carotid arteries for bruits (abnormal sounds).

Cardiac Cycle

  • Systole: Ventricles contract, blood is pumped out.
    • Right ventricle pumps to pulmonary arteries (pulmonic valve open)
    • Left ventricle pumps to aorta (aortic valve open)
  • Diastole: Ventricles relax, blood fills the ventricles.
    • Blood flows from right atrium to right ventricle (tricuspid valve open)
    • Blood flows from left atrium to left ventricle (mitral valve open)

Physical Exam: Auscultation

  • Aortic area: 2nd intercostal space (ICS), right sternal border
  • Pulmonic area: 2nd ICS, left sternl boarder
  • Tricuspid area: 3rd/4th ICS, left sternal border
  • Mitral area: 5th ICS, left midclavicular line

Cardiac Auscultation

  • Auscultate all listening areas for S1 and S2 heart sounds using the diaphragm of the stethoscope.
  • Auscultate at the apex with the bell of the stethoscope.
  • Diaphragm is better for detecting high-pitched sounds (S1, S2, S4, and most murmurs).
  • Bell is better for detecting low-pitched sounds (S3 and mitral stenosis).

Heart Murmurs

  • Timing: Systolic or diastolic?
    • Palpate carotid upstroke (occurs in systole) to help determine timing.
    • If the murmur coincides with carotid upstroke, it is systolic.
  • Duration:
    • Early/mid/late systolic (or holosystolic)
    • Early/mid/or late diastolic
  • Shape:
    • Crescendo: Increases in intensity
    • Decrescendo: Decreases in intensity
    • Both: Starts softly, increases then decreases ("diamond-shaped")
  • Quality: Harsh, musical, soft, blowing, or rumbling?
  • Pitch: High, medium, or low pitched?
  • Location: Where on the chest is the murmur loudest?
