2 - visceral (also called serous layer)
3 - parietal
4 - myocardium

A

2 - visceral (also called serous layer)

Q

Pericardial disease is due to an inflammation of the pericardium. Patients with acute pericarditis can present acutely. They can present with severe retrosternal chest pain that radiates to the neck, shoulders and back. It is worse with each breath as the expanding lungs compress the pericardium. Is the pain lessened when the patient is supine and lying or sitting and leaning forwards?

A
  • sitting and leaning forwards
  • reduces pressure on the pericardium

1 - globular cardiomegaly
2 - tracheal deviation
3 - cardiomegaly
4 - hyper-inflated lungs

1 - ST elevation
2 - PR depression
3 - sinus tachycardia
4 - small complexes (QRS height may fluctuate)

A

3 - sinus tachycardia
4 - small complexes

  • ECG leads are further away so lower voltage
19
Q

If the patient is haemodynamically stable, would a drainage of the pericardium be performed?

A
  • typically no
  • pericardiocentesis may be performed to diagnose though
20
Q

2 - if effusion if virally infected
3 - if cardiogenic shock occurs
4 - all of the above

A

3 - if cardiogenic shock occurs

21
Q

What is the main distinction between a pericardial effusion and cardiac tamponade?

1 - lower fluid levels restricting heart
2 - increased fluid restricting hearts ability to contract
3 - poor perfusion of coronary blood vessels
4 - increased CO2 build up

A

2 - increased fluid restricting hearts ability to contract
- tamponade is french for to plug up and smash
- lots of fluid means heart cannot contract properly

22
Q

If the fluid in the pericardial space continues to build up, can the fibrous layer expand to help with heart contractions?

A
  • no
  • relatively fixed so fluid is trapped, limiting how the heart can expand in size
23
Q

In cardiac tamponade what can happen to the heart chambers?

1 - RA and RV dilate
2 - LV and LA hypertrophy
3 - RA and RV diastolic collapse
4 - all of the above

A

3 - RA and RV diastolic collapse
- reduces ventricle filling

24
Q

In cardiac tamponade, we have something called Becks triad. Which of the following is NOT part of this triad?

1 - hypotension
2 - raised JVP
3 - collapsing pulse
4 - muffled heart sounds

A

3 - collapsing pulse

  • hypotension = reduced cardiac output
  • raised JVP = blood backing up
  • muffled heart sounds = fluid makes it harder to hear the heart sounds
25
Q

In addition to Becks triad, which other clinical signs from those here might we see?

1 - tachycardia
2 - kussmauls sign (increased JVP on inspiration)
3 - increased pulse
4 - all of the above

A

4 - all of the above

26
Q

When trying to diagnose a patient with a cardiac tamponade, we can perform an echocardiogram. What may we see?

1 - echo free zone around the heart
2 - increased resonance around the heart
3 - thickened myocardium
4 - ventricular regurgitation

A

1 - echo free zone around the heart

27
Q

If a patient has cardiac tamponade, is a drainage important?

A
  • yes
  • can cause cardiogenic shock and death
28
Q

All of the following are locations used when performing a pericardial drainage in a patient with cardiac tamponade, EXCEPT which one?

1 - right of the xiphoid process
2 - under the costal margin
3 - aim for the right mid clavicle
4 - aim of the left mid clavicle

A

3 - aim for the right mid clavicle

29

A
  • chronic
  • pericardium becomes thick and scarred
30
Q

Which of the following is NOT a typical cause of constructive pericarditis?

1 - idiopathic
