1

what is important to include in your physical examination of the cardiovascular system?

RMEPFCTA
R - respiration at rest
M - mucous membranes
E - external jugular vein exam
P - precordial palpation for cardiac apex beat
F - femoral arterial pulse evaluation (strength & reg)
C - cardiac and lung auscultation
T - thoracic precussion
A - abdominal palpation for hepatomegaly and ascites

2

what is the S1

caused by closure of AV valves at beginning of systole
lower and longer pitch than S2

3

what are pathologic conditions of S!

split S1 can be heard with conduction alterations, ventricular premature contractions or normal in large resting dog

4

what is the S2

caused by closure of outlet valves at end of systole
heard loudest over aortic arch
shorter and higher pitched than S1

5

pathologic conditions of S2

split S2 can occur due to delayed closure of pulmonic valve = pulmonary hypertension, right bundle branch block, ventricular premature beats, pulmonic stenosis

6

what is S3

passive filling of ventricles

7

pathologic conditions of s3

in dogs s3 associated with myocardial failure or severe mitral regurg.

8

what is s4

caused by atrial contraction at the end of diastole

9

pathology of s4

can be osculated in dogs and cats when atria dilate in response to ventricular stiffness such as in hypertrophic cardiomyopathy

10

systolic murmur

b/w S1 and S2

11

diastolic murmur

b/w S2 and S1

12

holosystolic murmur

can occur throughout systole but with both S1 and S2 still audible

13

pan systolic murmur

occur throughout systole but S1 and S2 not audible

14

diastolic murmur

usually heard in early diastole (just after S2) or through diastole

15

intensity

mild - hear both heart sounds and murmur in b/w
moderate - can't hear heart sound but hear murmur
severe - can palpate
