16
Q

Period when the AV valves are open

A

Valve status during diastole

17
Q

The QRS complex

A

Wave representing ventricular depolarization on the EKG

18
Q

Period when ventricles contract

A

During systole halfway through QRS complex

19
Q

Period on EKG of systole

A

From R- end of T wave.

20
Q

Period on EKG of diastole

A

From end of T wave until halfway through the QRS complex.

21
Q

What occurs between S1-S2

A

Systole’s position on the EKG

22
Q

Systole

A

Contraction phase of the heartbeat when blood is pumped from the chambers into the arteries

23
Q

Diastole

A

Relaxation phase of the heartbeat when the chambers to fill with blood

24
Q

What causes the semilunar valves to open?

A

Rapid ejection of blood during ventricular contraction

25
Q

The T wave

A

Wave representing Ventricular Repolarization on the EKG

26
Q

Passive ventricular filling

A

Phase 1, when atrial pressure forces AV valves open. Blood flows from atria to ventricles.

27
Q

Ventricular filling with atrial contraction

A

Phase 2, when atria contract to complete filling of the ventricles and ventricular diastole ends.

28
Q

Isolvolumetric contraction

A

Phase 3, when ventricles begin to contract and ventricular pressure increases, closing the AV valves.

29
Q

Ventricular ejection

A

Phase 4, when ventricular pressure continues to rise, causing an ejection of blood through the SL Valves

30
Q

Isolvolumetric relaxation

A

Final Phase (5), when pressure in the ventricles fall as they relax. SL valves close.

31
Q

Ventricular filling valve status

A

Ventricles: Relaxed/Diastole Atria: Relaxed/Diastole AV Valves: Opened SL valves: Closed

32
Q

Ventricular filling with atrial contraction valve status

A

Ventricles: Relaxed/Diastole Atria: Contracted/ Systole AV Valves: Opened SL valves: Closed

33
Q

Isolvolumetric contraction valve status

A

Ventricles: Contracted/ Systole Atria: Relaxed/Diastole AV Valves: Closed SL valves: Closed

34
Q

Ventricular ejection valve status

A

Ventricles: Contracted/ Systole Atria: Relaxed/Diastole AV Valves: Closed SL valves: Open

35
Q

Isolvolumetric relaxation valve status

A

Ventricles: Relaxed/Diastole Atria: Relaxed/Diastole AV Valves: Closed SL valves: Closed

36
Q

Equivalent to one heartbeat

A

Equivalent to one cardiac cycle

37
Q

Total heart relaxation

A

Quiescent period
