JVP Flashcards
Why Jvp is used to know about Right atrial pressures?
Direct connection of internal jugular vein to RA
No valves
a,c,x,v,y waves represents what?
a wave - atrial contraction c wave - tricuspid bulging x wave - atrial relaxation v wave - venous filling y wave - atrial emptying
Give 2 descent?
A-x descent - atrial relaxation
V-y descent - atrial emptying
Which descent/ascent represents venous filling?
Y-a ascent
In Which condition a wave will be absent?
Atrial fibrillation
2 atrial pathologies which will cause giant a wave?
Tricuspid stenosis
Right atrial myxoma
2 ventricular pathologies causing giant a wave?
Pulmonary stenosis
Pulmonary hypertension
Give 3 conditions in which you see canon a wave?
Complete heart block
Junctional rhythm
AV association with ventricular tachycardia
Which condition can cause reversal of x wave?
Tricuspid regurgitation
What clinical conditions can convert a negative x wave to positive one?
Tricuspid regurgitation
Name 3 conditions that can accentuate x wave on JVP graph?
Restrictive cardiomyopathy
Constrictive pericarditis
Cardiac tamponade
Increased amplitude of V wave on JVP can can be due to?
Tricuspid regurgitation
What are the 3 types of abnormalities seen in y wave of JVP?
Early deep y wave
Deep y wave
Slow deep y wave
What pathology can lead to early deep y wave on JVP?
Tricuspid regurgitation
What pathology can lead to deep y wave?
Constrictive pericarditis
Name 2pathologies that can lead to slow deep y wave?
Tricuspid stenosis
Right atrial myxoma
What are the three type of abnormalities in a-x descent?
Accentuated
Reduced
Reversed
What pathologies can lead to accentuated a-x descent on JVP?
Restrictive cardiomyopathy
Constrictive pericarditis
Cardiac tamponade
What pathology can lead to reduce a-x descent?
Right ventricular dilation
Which pathology can cause reversal of a-x descent?
Tricuspid regurgitation
What are the abnormalities of v-y descent?
Accentuated-Tricuspid regurgitation and constrictive pericarditis
Reversed- tricuspid stenosis and right atrial myxoma
What all abnormalities can be found if patient has tricuspid regurgitation?
Reversed x wave Increased amplitude of v wave Early deep y wave Reversed a-x descent Accentuated v-y descent
What abnormalities of JVP can be seen if a patient has tricuspid stenosis or right atrial myxoma?
Slow deep y wave
Reduced v-y descents
What cardiac conditions can increase JVP?
Rights heart failure Tricuspid regurgitation Tricuspid stenosis Cardiac tamponade Constrictive pericarditis
