This document provides an examination of the cardiovascular system. It begins with a general examination including vital signs. It then discusses signs such as pallor, cyanosis, clubbing, and edema. The document examines the pulse, blood pressure, jugular venous pressure, and auscultation of heart sounds. It provides details on normal and abnormal findings for each of these exam components. The document concludes with an examination of peripheral pulses and abnormalities of the jugular venous pulse.

The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

• Measured by “Sphygmomanometer”.
• Principle of sphygmomanometry –
Turbulant flow through a partially compressed artery
↓
Creates noises (Korotkoff’s sounds)
↓
Change in intensity correlates with systemic arterial pressures
46. Korotkoff’s sounds :-
• 5 phases;-
I – 1st appearance of clear, tapping sounds.
Represent SBP.
II – Tapping sounds are replaced by soft murmurs.
III - Murmurs become louder.
IV – Muffling sounds.
V – Disappearance of sounds.
Corresponds to DBP.
47. • In AR, diaspperance pt is very low.
sometimes 0mmHg.
So, Phase IV is taken as DBP.
• If Korotkoff’s sounds are not heard while recording.
Ask pt to raise the cuffed UL & ask to open & close the fist.
then record the BP.
48. Auscultatory gap :-
• Certain pt.s with HTN occaisionally;-
After initial appearance of korotkoff’s sounds, the sounds disap
for sometime & then reappear again &
finally disappear at DBP.
• Overestimates the DBP &
Underestimate the SBP.
• Thus, palpatory method must be used to confirm.

• does not peak around S2.
• Causes – AS with AR, PS with PR.
110. Systolico-diastolic murmur :-
• A murmur that occupies both systole & diastole,
• Occurs through different channels,
• does not peak around S2.
• Causes – VSD with AR.
111. Named murmurs :-
• A] Aortic valve –
• Gallavardin phenomenon Austin-Flint murmur

The Harsh noisy component of Low-pitched rumbling mid-di
ESM of AS, best heard at the apex,
Which is best heard at the in severe AR.
R sternal border, &
Radiated to the neck.
• Cole-cecil murmur :- Murmur of AR well heard in axilla.
112. • B] CAREY COOMB’s Murmur :- Short, mid-diastolic murmur
best heard at the apex in cases
with MS in Acute RHD.
• C] Graham Still murmur :- High-pitched, Early diastolic murmur,
best heard at the left sternal border 2nd IC
during expiration in PR.
• D] Carvallo’s sign :- Pan-systolic murmur of TR,
best heard in tricuspid area,
which becomes louder during inspiration.
• E] Gibbson murmur :- Continuous machinery murmur of PDA.
113. Dynamic auscultation :-
• Refers to the changes in haemodynamics by physiological &
pharmacological manouvres & the effect of these manouvres on
heart sounds & murmurs.
• Respiration,
• Valsalva manouvre,
• Standing to squatting,
• Isometric exercise.
114. Respiration :-
• During inspiration – R sided murmurs become louder &
L sided murmurs become softer or unchanged
• Expiration has the opposite effect.
115. Valsalva manouvre :-
• Close the nose with fingers & breath out forcibly with closed mou
against closed glottis.
