Questions and Answers
How does the presence of pericardial fluid affect the heart's function?
How does the presence of pericardial fluid affect the heart's function?
- It allows the heart to generate electrical impulses more efficiently.
- It can restrict ventricular filling, potentially leading to decreased cardiac output. (correct)
- It directly strengthens the myocardial contractions, leading to increased cardiac output.
- It enhances the heart's ability to pump blood by providing extra lubrication.
Why is an echocardiogram considered the confirmatory diagnostic test for pericarditis?
Why is an echocardiogram considered the confirmatory diagnostic test for pericarditis?
- It is non-invasive and can directly visualize the pericardium, detecting effusions or thickening. (correct)
- It can quickly rule out all other possible cardiac conditions, confirming pericarditis by exclusion.
- It provides a detailed analysis of the electrical activity of the heart, pinpointing the exact cause of inflammation.
- It measures specific blood markers that are elevated only in cases of pericarditis.
What causes the relief of chest pain when sitting up and leaning forward in patients with pericarditis?
What causes the relief of chest pain when sitting up and leaning forward in patients with pericarditis?
- This position reduces the heart rate, decreasing the oxygen demand of the myocardium.
- This position increases blood flow to the heart muscle, alleviating ischemia.
- This position promotes better lung expansion, reducing pressure on the heart.
- This position minimizes contact and friction between the inflamed pericardium and surrounding structures. (correct)
Why is diabetes mellitus often considered a risk factor for cardiovascular complications, but not typically for pericarditis?

Study Notes
- The primary function of the pericardium is to act as a membranous sac that protects the heart.
- Viral infections are most commonly associated with pericarditis.
- Pericarditis restricts ventricular filling, leading to decreased cardiac output.
- An echocardiogram (2D Echo) is considered the confirmatory diagnostic test for pericarditis.
- A pericardial friction rub is a hallmark sign of pericarditis that can be heard during auscultation.
- Sitting up and leaning forward typically relieves chest pain in pericarditis.
- Diabetes mellitus is not a risk factor for pericarditis.
- Pericardial effusion is fluid accumulation in the pericardial sac.
- Beck's triad is associated with cardiac tamponade.
- Bradycardia is not part of Beck's triad.
- Constrictive pericarditis is characterized by a thickened and less elastic pericardium, restricting heart movement.
- The primary treatment goal for pericarditis is to reduce inflammation and relieve pain.
- Ketorolac is a medication commonly used to treat pericarditis pain and inflammation.
- Pericardiocentesis is the procedure that involves the aspiration of excess fluid from the pericardial sac.
- Constrictive pericarditis is a complication of pericarditis that leads to restricted ventricular filling and systemic venous congestion.
