What should you look at in the eyes and face for CV Exam

What vein do you use to assess the JVP?
Internal Jugular Vein
It is valveless unlike the external jugular
Why assess the JVP?
The internal jugular vein reflects the pressure and function of the right side of the heart and thoracic cavity.
It gives information on circulatory volume and right ventricular function.
Causes of a raised JVP
Overfilled Right Atrium ..Fluid Overload ..Right Ventricular Failure ..Pregnancy Right Ventricular Compression ..Cardiac Tamponade ..Constrictive pericarditis Increased intrathoractic pressure leading to right heart failure ..Pulmonary HTN ..Pulmonary Oedema ..Tension Pneumothorax Tricuspid Valve Disease ..Stenosis ..Regurgitation ..Cardiac Myxoma Superior Vena Cava Obstruction ..Lung Tumour ..Mediastinal Masses ..Large Thyroid Goitre

Heart Block
What is the Second Heart Sound?
Closure of the Aortic (followed by Pulmonary) Valve
What is the Third Heart Sound?
Sometimes called Gallop Rhythm.
Due to rapid LV filling in diastole.
Can be normal in young healthy athletic adults.
Also seen in heart failure and mitral regurgitation
What is the forth heart sound?
Always pathological.
Amyloidosis, Aortic Stenosis, Hypertension.
Due to forceful atrial contraction against stiff left ventricle
Grading System for Murmurs
PAGE 45
Ejection systolic murmur of AS heard best in Mitral Region
Galavardin Phenomena
Characteristic Murmur of Mitral Regurgitation
Pansystolic murmur heard best in the mitral region. Radiating to the axilla.
Characteristic Murmur of Mitral Stenosis
Mid diastolic murmur. No radiation. Heard best in left lateral position in the mitral region.
Characteristic Murmur of Aortic Regurgitation
Early Diastolic Murmur. Heard best sitting forward in tricuspid region.
May radiate to apex.
Characteristic Murmur of Tricuspid Regurgitation
Pansystolic Murmur heard best in tricuspid region
Characteristic Murmur of Ventricular Septal Defect
Ejection Systolic Murmur heard best in the tricuspid region
Characteristic Murmur of Pulmonary Stenosis
Ejection Systolic Murmur. Loudest in Pulmonary area on inspiration.
Characteristic Murmur of Aortic Stenosis
Ejection Systolic Murmur. Loudest on right sternal edge. May radiate to carotids.
Characteristic Murmur of Aortic Sclerosis
Ejection Systolic Murmur. Loudest on right sternal edge. Doesn’t radiate to carotids.
Cardiovascular Disease associated with Ankylosing Spondylitis
Aortic Regurgitation
Name that CV sign: Pulsatile Liver
Tricuspid Regurgitation
Name that CV sign: Splenomegaly
Infective Endocarditis
To complete my cardiovascular examination…
To complete my cardiovascular examination I would like to do a brie examinaiton of the abdomen specifically looking for hepatomegaly, Pulsitlie liver and splenomegaly.
I would also like to perform a peripheral vascular examination and perform fundoscopy to assess for signs of infective endocarditis, hypertensive and diabetic retinopathy.
I would also like to examine any observation charts available for pulse, blood pressure and temperature and do a urine dip.
Finally I would like to do a 12 lead echocardiogram and order a chest X Ray with a posterior anterior view.
Name that CV sign: Hepatosplenomegaly
Right Heart Failure
How do you distinguish the JVP from the Carotid Pulse
The JVP, unlike the carotid pulse:
- Has a double pulsation (the ‘a’ and ‘v’ wave)
- Is impalpable
- Can be obliterated by light pressure applied at the root of the neck
- JVP rises momenterily with the hepatojugular reflex
- The JVP height varies with respiration (falls with inspiration)
What are the two main waveforms of the JVP?
The a wave: represents arterial contraction
The v wave: represents venous return during tricuspid valve closure.
What is Kussmaul’s sign and when is it seen?
Kussmauls sign is the paradoxical rise of the JVP during inspiration.
Normally JVP falls during inspiration becuase the intrathoracic pressure becomes increasingly negative increasing the blood flow back to the heart, however, when the right atrium fails to accommodate the increased venous return the JVP rises.
It is seen in Cardiac Tamponade, constrictive pericarditis and severe asthma.
DDx that sign: Loss of ‘a’ wave in JVP
Atrial fibrillation- wave lost due to ineffective atrial contraction.
DDx that sign: Cannon Waves
These are giant ‘a’ waves seen in the JVP during complete heart block.

Causes of commonly heard murmurs

What is reverse splitting of the Second Heart Sound (S2)?
A phenomenon where there is significant delay in left ventricular emptying such that the aortic valve closes after the pulmonary valve.
It is detected when splitting is heard on expiration but come together on inspiration.
Associated with LBBB, Hypertrophic Cardiomyopathy and right ventricular pacing
What are some indications for Pacemakers?
Pacemakers are most often due to atriventricular block such as third degree heart block with bradycardia or long periods of asystole, sick sinus syndrome with symptomatic bradycardia and symptomatic second degree heart block.
Symptoms include pre-syncope, syncope (Stokes-Adams) Confusion and seizures; related to the bradycardia.
What would you look for on a CXR of a patient with a recently inserted pacemaker?
Rarely, patients may have had an iatrogenic pneumothorax.
Other complications of pacemakers include: pacemaker failure, infection and electromagnetic interference.
