JVP & ECG Flashcards
5 Waves of JVP
A C-XVY
Atrial contraction wave
A wave (JVP)- upward deflection
which JVP wave is absent in AF (atrial fibrillation)
A wave (JVP)- upward deflection
RV contraction wave
C wave (c)ontraction
Closed Tricupsid valve budging into Atrium
C wave
Which valve in closed during C wave?
Tricuspid valve
C wave
bulging of tricuspid into the right atrium during ?
Isovolumetric Systole
downward displacement of closed Tri Valve during
RAPID VENTRICULAR EJECTION PHASE
X wave (descent)
- Tricuspid Regurgition
- right HF
reduced pressure gradients
-Which JVP wave are TRICUSPID REGURGITION, or R HF absent/ reduced
X wave
V wave (jvp) increased ? Pressure
Increased RA pressure
Due to filling against closed Tricuspid valve
“v-illing”
Increased RA pressure from Filling
Against Tricuspid Valve
RA emptYing into RV
Y descent (jvp)
Prominent Y wave?
constructive pericarditis
Absent Y wave
cardiac temponade
Automaticity location?
Cells Depolarize themselves
SA node ( RA)
Band of Tissue/ Highway wave transfers Depolarization to LA
Bachmann’s Bundle
SA node to AV node connection
between atria and ventricle
Internodal Tracts
0.1 s delay in contraction between ATRIA & VENTRICLE is due to:
Atrioventricular node
Purpose of 0.1s delay between Atria & Ventricle contractions is for which purpose:
Allows movement of blood within the same direction (as opposed to both ways
AV node travels to:
Bundle of His
Bundle of His travels to:
R & L bundle
Bundle of His travels to R & L Bundle thru
R & L Posterior & Anterior Fascicle
Area below Bundle of His before dissected to R & L bundle refers to:
L bundle
R & L Posterior & Anterior Fascicle travel to:
Purkinje Fibers
waves travel thru ? from
SA node
Bundle to His
Internodal Tracts
When do you measure Intravenous Pressure?
End of Exhalation
Decrease Pressure in Atrium?
Atrial Relaxation
Tricuspid Valve Open
Increase Pressure in Atrium
Atrial Contraction
Tricuspid Valve Closure
Ventricular Systole JVP wave
C wave
Atrial Systole JVP wave
A wave
Atrial Relaxation Wave JVP
X wave
Tricuspid Valve close JVP wave
C wave
Tricuspid Valve open JVP
X wave
Filling of RA wave JVP
V wave (filling)
RV filling Wave
Y wave
Ventricular Contraction
C wave
