Q

List Geriatric Cosiderations

A
  • Age alters the cardiovascular response to physical and emotional stress.
  • Heart valves become thick and stiff (tricuspid, mitral, pulmonary and aortic)
  • Frequent need for pacemaker as well as replacing pacemaker
  • Increase in SBP; decrease or no change in DBP

16
Q

This is accomplished by contraction and relaxation of the cardiac muscle tissue in the myocardium layer.

A

Conduction

17
Q

The electrical conduction system controls the heart rate

A

Cardiac conduction system

18
Q

Explain conduction in the sinoatrial node

A

Located in the back wall of the right atrium near the entrance of vena cava,
Initiates impulses 70-80 times per. In without any nerve stimulation from brain. ( normal pulse is 78-82)
Establishes basic rhythm of the heartbeat
This is where the pulse rate is

19
Q

Called the pace maker of the heart

A

Sinoatrial node

20
Q

Impulses move through atria causing two atria to contract

A

sinoatrial node

21
Q

At the same time. Impulses reach the second part of the conduction system

A

Sinoatrial Node

22
Q

Located in the bottom of the right atrium near the septum.

A

Atrioventricular Node

23
Q

What does cells in the AV node do?

A

Conduct impulses more slowly, so there is no delay as impulses travel through the the node

24
Q

Allows time do aria to finish contraction before ventricles begin contacting

A

Atrioventricular Node

25
Q

What does the AV bundle branch form and what does it do?

A

The AV bundle branch to form the Purkinjie fibers that transmit the impulses to the myocardium

26
Q

Muscle tissues

A

Myocardium

27
Q

The function of the bundle of his, bundle branches and Purkinjie fibers

A

Transmits quickly and cause both ventricles to contract

28
Q

What like a phone tree

A

The bundle of His, bundle branches , and the Purkinjie fibers

29
Q

From the AV node, impulses travel through right and left and

A

Left bundle branches and these branches extend to the right and left sides of the septum and the bottom of the heart

30
Q

As the ventricles contract what’s happens and what is this called?

A

As the ventricles contract, blood is forced out through the semilunar valves into the pulmonary trunk and the aorta.

31
Q

What happens after the ventricles complete their contraction phase?

A

They relax and the SA node initiates another impulse to start another cardiac cycle.

32
Q

What does the conduction systems consist of?

A

1- Sinoatrial node (SA)
2- Atrioventricular node (AV node)
3- Bundle of His
4- Right & Left Bundle Branches which lead to the Purkinje fibers
