Inguinal glands: palpate horizontal chain just below the inguinal ligament
and vertical chain along the saphenous veins.
Popliteal glands: use both hands to examine the popliteal fossa with the knee flexed to less

Pulse
? It is expansion and elongation of the arterial wall imparted by the column of
blood and is passively produced by the pressure changes during ventricular
systole and diastole.
? Points to note:
1.Rate
2.rhythm
3.volume
4.condition of the arterial wall
5.radio-radial delay
6.radio-femoral delay
7.any special character
8.palpation of other peripheral pulses



? Examination:
* The radial pulse at the right wrist of the patient,present lateral to the flexor carpi radialis tendon,generally
examined with the pulp of three fingers(index,middle,ring finger).
*Patient's forearm wil be semipronated and the wrist slightly flexed.
*rate and rhythm are better palpated in the radial artery.
*volume and character better understand in carotid artery
1.Rate : normal 60-100/min
1. bradycardia HR <60
causes: physiological: elderly(due to SA node degeneration)
sleep( due to decreased adrenergic drive)
athlets( increased vagal discharge)
pathological: bradyarrhythmia
inferior wall AMI
hypothyroidism
hypothermia
drugs( beta blockers,non DHP CCB,digoxin)
raised ICT(cushing reflex)
obstructive jaundice



Relative bradycardia: heart rate does not increased in proportion to body
temperature.it is also called faget's sign.
normally for every 1C rise in temperature from baseline, HR increased by 15-
20 /min.
for every 1F rise,HR increased by 10/min
Causes:
infectious: typhoid
brucella
viral fever
legionella
non infectious: drug induced fever

hyperthyroidism
fever,heperthermia,hyperpyrexia
drugs( beta agonist,DHP CCB,thyroxin overdose,theophylline)



2.Rhythm: normally there is fixed interval between two consecutive pulses,it is called regular
rhytm.
? Sinus arrhythmia:
-pulse interval changes with respiration.
-It is predictable variation
-HR increases with inspiration,HR decreases with expiration
Irregular rhythm-commonly seen in AF
3.volume: it reflects the width of pulse pressure.
normal level=(SBP-DBP)=(30-60)mm of Hg
a)low volume: called as thready pulse(<30 mm of Hg)
seen in shock ( hypovolemic,cardiogenic)
b)high volume: called as bounding pulse(>60 mm of Hg)
seen in AR,MR,PDA,Pregnancy,hyperthyroidism,anaemia,AV fistula,paget's
disease,beri beri




Percussion wave- due to isovolumetric
contraction
Anacrotic notch- due to opening of semilunar
valves
Tidal wave- ejection phase,amplitude depends
on cardiac output
Dicrotic notch- due to closure of semilunar valve



? 4.character:
a) Anacrotic pulse: low volume pulse with an upstroke felt in the ascending limb of pulse
wave.
e.g.-severe valvular aortic stenosis.it is known as pulsus parvus et tardus(slow rising low
volume pulse)
b) Dicrotic pulse: upstroke felt in the descending limb of the pulse wave.
e.g.-hypovolemic shock
c)Pulsus bisferiens: two peaks in systole.
e.g.-combined AR and AS
severe AR
d)Pulsus alternans: regular alteration of pulse amplitude at same interval.
e.g.- LVF
e)Pulsus bigeminus: two beats and a pause occur repeatedly in regular fashion.
e.g.-digitalis toxicity
f)Pulsus paradoxus: normally (SBPexp ?SBPinsp ) =0 to 10 mm of Hg
if this difference is >10 mm of Hg it is pulsus paradoxus.
mechanism: due to decrease in SBP in inspiratory phase more than physiological limit.it occurs
due to LV filling decreases during inspiratory phase more than physiological limit.



? Causes of pulsus paradoxus: cardiac tamponade
constrictive pericarditis
restrictive cardiomyopathy
acute severe asthma/COPD
pulmonary thromboembolism
SVC syndrome
g)Water hammer pulse: it is characterised by-high volume
sharp rise
ill sustained
sharp fall

PDA
systolic HTN
fever
pregnancy
anaemia
beri beri
thyrotoxicosis
AV fistula
paget's disease



? Demonstration of water hammer pulse:
palpate the wrist in such a way that webs of palm fell on the radial
artery and rest of the palm lies over the ulner artery.
Examine the volume of the pulse for few seconds.
Now elevate the whole upper limb suddenly above the level of the
heart.
Try to recognise any changes in the volume of the pulse.



5.Radio-radial delay: normal anatomical variation
thoracic inlet syndrome
aneurysm of the arch of aorta
pre-subclavian coarctation
supravalvular aortic stenosis
takayasu disease
6.Radio-femoral delay: coarctation of aorta
atherosclerosis of aorta
thrombosis or embolism of aorta
aortoarteritis
7.Other peripheral pulses: carotid artery
brachial artery
femoral artery
popliteal artery
posterior tibial artery
arteria dorsalis paedis
8.Condition of arterial wall: normally the arterial wall is impalpable and may be palpable in old age due
to arteriosclerosis.

? Subnormal: below 98F
? Hypothermia:below 95F
? Pyrexia/febrile:oral AM temperature >98.9F, oral PM temperature >99.9F
? Hyperpyrexia:above 106.7 F
? Types of fever

b)acute broncho pneumonia
c) acute tonsillitis
d)amoebic liver abscess

Neck vein
? Examination:
? Always examine internal jugular vein.it is in direct continuity with the
right atrium and reflects the pressure changes in the right atrium as
well as CVP.
? The patient should be reclining supine at 45
? Neck muscle should be relaxed properly
? Tangential light application is better to visualise the wave.
? It is better to examine right sided vein.
? Stand on the right side of the patient and turn patient's face slightly to
the left.
? Look in between two heads of sternocleidomastoid muscle,and if it
seems full, observe uppermost point of distension.



? Characteristics of venous pulsation:
1.wavy
2.better seen than felt
3.becomes prominent on expiration,on lying down,on application of
abdominal pressure(hepato jugular reflux)
4.can be abolished by gentle digital pressure applied above the clavicle.
5.it has definite upper level.
6.pulsatile displacement of ear lobes in high CVP
7.Becomes prominent on valsalva manoeuvre




a wave- produced due to effective and synchronised
contraction of right atrium
c wave- isovolumetric contraction of right ventricle.
tricuspid valve bulge into the right atrium due to
increased pressure.
x wave- ejection phase
v wave -due to venous return in right atrium.
isovolumetric relaxation also occurs here.
y wave- due to early filling phase of diastole.



? Causes of increased JVP:
Engorged and pulsatile:1.congestive cardiac failure
2.chronic constrictive pericarditis
3.cardiac tamponade
4 TI and TS
5.restrictive cardiomyopathy
Engorged and non pulsatile:superior mediastinal syndrome
hepato jugular reflux: patient reclining at 45 firm pressure is applied over
right hypochondrium for 10 sec sustained rise of >3cm in JVP for at least 15
sec
importance: -to diagnose incipient right heart failure
-to differentiate between arterial and venous pulsation
-to differentiate between obstructive and non-obstructive causes
of engorged neck vein.



? Waves of JVP:
? Absent `a' wave: in atrial fibril ation
? Large `a' wave: TS,RVH,RVF
? Canon `a' wave: SA node arrest,complete AV block
? Absent `x`descent: TR,AF
? Deep' x' descent: cardiac tamponade
constrictive pericarditis
restrictive cardiomyopathy
Absent/low `v' wave: SVC obstruction
Large' v' wave: constrictive pericarditis
restrictive cardiomyopathy
TR
AF
Rapid `y' descent: constrictive pericarditis
Slow `y' descent: TS,RVH,RVF
Absent `y' descent: col apsed RV due to cardiac tamponade



? Kussmaul sign:
Normally JVP decreases during inspiration.but if JVP rises during
inspiration due to failed relaxation of right atrium it is called kussmaul
sign.
causes: constrictive pericarditis
restrictive cardiomyopathy
severe TS
RVF
