Download Cardiac Examination

Cardiac Examination
A. General
- observe for central or peripheral cyanosis (pinkish/bluish nail beds), clubbing of fingers and toes,
xanthomas, xanthelasmas, splinter hemorrhages, diaphoresis (MI)
B.
Vital Signs
- check blood pressure (both arms {normal diff bet 2 sides is < 10 mm Hg}, supine and upright)
- check arterial pulse (radial)
1. rate (over 15 sec x 4)
2. rhythm (ex. Regular, regularly irregular {PAC’s, PVC’s}, irregularly irregular(Afib})
3. volume/amplitude (ex. weak {heart failure}, bounding pulse {thyrotoxicosis})
4. symmetry on both sides
C. Neck Inspection
1. Elevate the bed at 30-45 degrees before asking the patient to lie down
2. palpate carotid pulsation on both sides with your thumb
3. check jugular venous pulsation
- head slightly turned away from the midline, use tangential lightning (“look away from me”)
- comment on how high JVP (normally upto 2-3 cm from the sternal angle) and
the timing of the a wave & v wave with respect to the heart sounds
- know how to differentiate between an arterial vs venous pulsation
3. listen for carotid bruit..
D. Precordial Inspection (do so from the foot of the bed)
- observe for any thoracic cage deformities, venous dilatation of the skin, respiratory difficulties check for
visible apex beat, heaves, lifts, retractions
E. Precordial Palpation
- palpate the precordium at four sites with your index finger:
1. aortic site
2. pulmonic site
3. Erb’s point (3rd ICS RSB where both aortic and pulmonic sounds are audible)
4. tricuspid site
5. mitral site
comment on any palpable thrills, lifts, pulsations
- comment on the apex beat: (apex beat is the lateral most pulsation vs PMI)
1. location (should not be > 4 inches lateral to the LMCL)
2. size (should not be > 2 cm in diameter)
3. quality (strong or weak)
4. duration (<2/3 of systole) (done while simultaneously listening at the heart sounds at the base)
- palpate the epigastrium for the abdominal aorta
F.
Auscultation
- listen to the heart in the ff locations (rub the stethoscope with your hands to warm it up):
1. aortic site
2. pulmonic site
4. Erb’s point (3rd ICS RSB where both aortic and pulmonic sounds are audible)
5. tricuspid site
6. mitral site
- listen to the heart sounds with both diaphragm (S1,S2, systolic murmurs) ( move from point 1 to 5) and bell
(S3, S4, diastolic murmurs) (from point 5 to 1)
- comment on S1, S2, S3, S4
- location, where is it loudest
- splitting
- intensity
- comment on the murmur
A. grading:
1. soft murmur, faintly heard
2. soft murmur, readily heard
1
-
3. loud murmur, w/o thrill
4. loud murmur w/ thrill
5. murmur heart with only edge of stet touching the chest
6. murmur heart with stet not touching the chest wall
B. radiation
- AS radiates to the neck
- MR radiates to the axilla
C. timing (systolic, diastolic, continuous)
D. location
E. effect of manuevers on intensity of heart sounds
AR inc when sitting upright
inc on expiration
MS inc when turning to LLD
Right sided murmurs – inc with inspiration
AS - dec with valsalva’s (blow hard at back of your hand)
F. Shape (blowing, crescendo, diamond shaped)
G. Quality
H. Pitch
Maneouvers:
1. LLD: “I’d like to listen to your heart in a different position, can you turn to your left side please”
and ask patient to “breathe in deeply, breathe out and hold it” listen with the bell from a mid
diastolic events murmur of Mitral Stenosis at apex
2. upright, : “I’d like you to lean forward” “take a deep breath and hold it”: listen with diaphragm
over the aortic area and L sternal edge for high pitched blowing early diastolic murmurs of Aortic
Regurgitation.
G. Additional Tests
Pulsus Paradoxus
1. Determine the systolic BP by palpation
2. Inflate the BP cuff 30 mm Hg above the palpable systolic BP
3. Deflate the cuff slowly, as the cuff pressure is slowly lowered, the sounds appear to double
( they become audible in inspiration as well as expiration)
4. the difference in systolic BP recorded at the start of the Korotkoff’s sounds in inspiration and
is an estimate of pulsus paradoxus (it is significant if it is greater than 10 mm Hg
expiration
H. Auscultate the Lungs
in at least 4 places
I. Abdominal Exam
- check for hepatojugular reflux if suspecting CHF
1. warn px first before pressing
2. instruct px to breathe normally during pressure
3. place palm over the abdomen
4. compress abdomen steadily for 10 sec
5. note any change in JVP during abdl pressure and at the time of release
- check for abdominal bruits (if suspicious of abdominal aortic aneurysm)
- percuss for ascites
J. Inspect the Legs and sacral area
- check for pitting edema
- palplate peripheral pulses
- check for calf tenderness (people w/ heart failure have inc risk for DVT)
