Inspection

  • from the FOOT of the bed
    • chest wall DEFORMITY (pectus excavatum, carinatum)
    • SCARS (thoracotomy, pacemaker)
    • HEAVES (ventricular hypertrophy) and lifts
    • visible apical beat
    • IMPULSES (under xiphoid – can mean RVH or Aorta).

Palpation

  • using FINGER PADS, palpate for APEX impulse (PMI) - accurately measure MCL
    • LOCATION, SIZE - one ICS
    • AMPLITUDE - if increased, suggests volume/pressure overload
    • DURATION - check in relation to carotid pulse (> 2/3 systole → sustained, LVH)
    • if carotid is delayed = parvus et tardus → AV stenosis
  • THRILLS - palpate at each of the 4 valve zones = grade 4 murmur
  • HEAVES (with HEEL of hand)
    • left sternal border → LVH
    • PV → pulmonary hypertension
    • AV → systemic hypertension
    • inferior to XIPHOID - RVH

Auscultation

  • listen specifically for one sound at a time
  • calibrate your timing to the radial pulse
  • S1 > S2 in LLSB
  • S2 > S1 in LUSB

S1

  • louder → ↓ PR interval, ↑CO, ↑HR
  • quieter → ↑ PR interval, MR, severe MS
  • splitting → RBBB

S2

  • splitting ↑ by continued INSPIRATION (while patient not holding in breath)
  • LOUD S2 → hypertension (systemic or pulmonary circulation)
  • WIDE SPLIT S2 - RBBB, PS
  • FIXED SPLIT - ASD
  • PARADOXICAL: LBBB, severe AS

S3 (VENTRICULAR GALLOP)

  • lightly use bell at apex, best heard in LLD
  • can be normal in young people and the pregnant
  • noted in volume overload, increased transvalvular flow (TR, MR)

S4 (ATRIAL GALLOP)

  • lower pitched
  • indicates stiff LV– LVH, post-MI

Other sounds

Ejection click - between S1 and S2 Carotid bruit Pericardial friction
