1. Look at the tracing of volume.

Explain what the end diastolic volume is?

2. Look at the tracing of the ECG. What events come immediately before the end diastolic volume?

3. Look at the heart sounds tracing. What does S1 represent? What is the status of the tricuspid and bicuspid valve (AV valves).

4. Look at the pressure tracing at the time of s1. Examine the line for left ventricular pressure. What is happening to the pressure?

5. Look at the tracing of volume.

Explain what the end systolic volume is and what events bring this about?

6. Look at the heart sounds tracing. What does S2 represent? What is the status of the aortic and pulmonary semilunar valves?

7. Look at the pressure tracing. Examine the line for left ventricular pressure and aortic pressure.

a. What happens to left ventricular pressure to allow the opening of the semilunar valves?

b. What is happening at the time of the dicrotic notch?
