2
Q
c wave
A
RV contraction (closed tricuspid valve bulging into atrium)
3
Q
x descent
A
atrial relaxation and downward
displacement of closed tricuspid valve during ventricular contraction.
Absent in tricuspid
regurgitation.
Prominent in tricuspid
insufficiency and right HF.
4
Q
v wave
A
INC right atrial pressure due to filling (“villing”) against closed tricuspid valve.
