Cardiac Cycle Flashcards
1
Q
What is the a wave
A
Contraction of the atria
2
Q
What is the v wave
A
The pressure change generated as the atria fill with blood
3
Q
What is the x descent
A
The x descent follows the a wave and represents decreased pressure as blood flows into the atrium
4
Q
What is the y descent
A
The y descent follows the v wave and represents decreased pressure as blood flows into the ventricle.
5
Q
What is the c wave
A
This represents bulging of the atrioventricular valves into the atria during ventricular contraction.
