The cardiac cycle

Question 1

Define late diastole

Answer 1

AV valve open but semilunar close

Ventricle fill passively due to high P in atrium

Question 2

Define atrial systole

Answer 2

AV open and Semilunar close

Contraction of atrium

Question 3

Define isovolumetric ventricular contraction

Answer 3

AV close and semilar Close

Although ventricle is full, the pressure in aorta is still higher

Question 4

Define ventricular ejection or early ventricular diastole

Answer 4

AV close and semilunar open

Contraction occurs and eventually the P of ventricle exceeds that of aorta

Question 5

Define the a wave

Answer 5

Atrial systole

Question 6

Define the c wave

Answer 6

The tricuspid valve being pushed back

Question 7

Define the v wave

Answer 7

atrium filling passively

Question 8

When do you hear LUB?

Answer 8

When the mitral and tricuspid valve close

Question 9

When do you hear DUB?

Answer 9

When the aortic and pulmonary valve close

Question 10

When might you hear aortic/pulmonary stenosis or mitral/tricuspid regurgitation?

Answer 10

Between S1 and S2

ventricular systole

Question 11

When might you hear mitral/tricuspid stenosis and aortic/pulmonary regurgitation?

Answer 11

Between S2 and S1

ventricular diastole
