Q

Collapsing pulse

A

Happens in AR
water hammer pulse is felt as a tapping impulse that is transmitted through the bulk of the muscles.
This happens because the blood that is pumped to the arm during systole is emptied very quickly due to the gravity effect on the raised arm.
This results in the artery emptying back into the heart during diastole, increasing preload, and therefore increasing cardiac output

Q

Steps in cardio exam before auscultate heart? part 1

A

1)Wash hands, introduce +consent, position , expose
2)General inspect- oxygen devices, click, distress, cyanosis( start thinking of pathology here already)
3)Hands- do with pulse together
Radial pulse- radial radial delay, radio femoral delay
( is it okay if I feel the pulse in your groin)
collapsing pulse- do you have any pain in your shoulder? I am going to lift your hand.
4)BP- I am gonna take your blood pressure
5) eyes: look up for me and pull eyelid down
6) open your mouth wide- cyanosis and high arched palate
7) turn your head slightly to your left, ask if you have any pain in your tummy, i am going to press gently for hepatojugular reflex
8) feel pulse in your neck -both sides one at a time

Q

steps after inspection in cardio exam? part 2

A

1) inspect chest for deformities, scars, insertable cardiac monitor devices site
2) feel for apex beat and count the ribs to confirm position
3) heel for parasternal heaves and palms for thrills( aortic and pulmonary area), then finger over remaining two valve areas-mitral and tricuspid
4) diaphragm over mitral area- take big breath in, hold your breath, big breath out, stop breathing , breathe normally, repeat at axilla
5) turn to left, bell over mitral area and repeat
6) lie flat- diaphragm in remaining 3 areas and repeat
7) ask to sit up, and palpate for palpable thrills over aortic pulmonary area
8) diaphragm over left sternal edge( for AR) and aortic area( AS)same method, and do at carotids again
9) do handgrip and valsava manourvre over mitral and aortic area
10) examine back and lower limbs and then thank patient

Q

what are blue patients?

A

eisenmeger syndrome, VSD,ASD,PDA, TOF

22
Q

Noonan syndrome

A

Pulmonary stenosis

23
Q

How do you check thrills?

A

if thrill coincides in time with apex beat- systolic thrill and if does not coincides, then it is diastolic thrill

24
Q

Explain 1st heart sound

A

closure of mitral and tricuspid valves
beginning of ventricular systole

25
Q

explain 2nd heart sound

A

softer, shorter
closure of aortic and pulmonary valves
marks beginning of diastole
sometimes can have splitting of 2nd heart sound in pulmonary area as pulmonary valve closure delayed with inspiration due to increased venous return to the right ventricle

26
Q

causes of loud S1( 2)

A

mitral stenosis
tachycardia- reduce diastolic filling time

27
Q

causes of soft S1? ( 3)

A

due to prolonged diastolic filling ( first degree HB)
delayed onset of left ventricular systole
MR

28
Q

causes of loud S2?

A

loud A2 in hypertension & aortic stenosis
loud P2- in pulmonary HTN

29
Q

soft A2?

A

in AR, calcified aortic valve

30
Q

when does increased normal splitting of 2nd heart sound occur?

A

pulmonary stenosis
VSD
MR
( increased in normal splitting on inspiration)

31
Q

fixed splitting 2nd heart sound, no variation with respiration?

A

ASD

32
Q

when does reversed splitting occur?

A

P2 comes first, then splitting occur in expiration
due to severe AS
coarctation of aorta

33
Q

what is 3rd heart sound?

A

low pitched, mid diastolic sound - like gallop rhythm( Kentucky)
due to reduced ventricular compliance
left ventricular S3 heard loudest at apex and on expiration- due to LVF, AR, MR,VSD, PDA
right ventricular S3- loudest at left sternal edge with inspiration- due to RVF , constrictive pericarditis

34
Q

what is 4th heart sound?

A

late diastolic sound pitched higher than S3( Tennessee), due to high pressure atrial wave reflected back from a poorly compliant ventricle
left ventricular S4- AS, MR, HTN, IHD, advanced age
right ventricular S4- pulmonary HTN, pulmonary stenosis

35
Q

what is opening snap?

A

high pitched sound in MS, best heard in lower left sternal edge with diaphragm

36
Q

what is systolic ejection click?

A

early systolic high pitched sound heard over aortic or pulmonary
in AS, PS

37
Q

non ejection systolic click?

A

high pitched sound hearing in systole best in mitral area

38
Q

pansytolic murmurs

A

MR
TR
VSD

39
Q

midsystolic murmurs

A

AS or aortic sclerosis
PS
HCM
ASD

40
Q

late systolic murmur

A

papillary muscle dysfunction
MVP

41
Q

early diastolic murmur

A

AR
PR

42
Q

mid diastolic

A

MS
TS
atrial myxoma
austin flint murmur of AR

43
Q

continuous murmur

A

PDA
AV fistula

44
Q

pericardial friction rub

A

superficial scratching sound, not confined to diastole or systole
often louder when patient sitting up or breathing out

45
Q

grading of murmur

A

grade 1/6- very soft, not heard at first
2/6- soft, but detected immediately
3/6- moderate, no thrill
4/6- loud, thrill just palpable
5/6- very loud, thrill easily palpable
6/6- very very loud, can heard without placing stethoscope

46
Q

effect on respiration on murmur

A

RIN- right sided increase with inspiration
left sided- increase with expiration

47
Q

special manoeuvres?

A

1) left lateral position- MS heard best with bell, if still cant listen, need to exercise the patient and hear again
2) lean forward in full expiration- AR can be heard best and pericardial friction rub also
3) valsalva - forceful expiration against closed glottis, listen over left sternal edge- louder for HCM, mitral area for MVP where systolic click and murmur begin earlier and last longer
4) sustained hand grip- MR murmur louder

48
Q

causes of pitting unilateral LL edema?

A

DVT
compression of large veins by lymph nodes or tumours

49
Q

causes of non pitting LL edema?

50
Q

51
Q

features of chronic constrictive pericarditis?

A

cachexia
pulses paradoxus ( more than 10mmHg fall in arterial pulse on inspiration), low BP
JVP raised, kussmaul signs

early pericardial knock
hepatomegaly
