27
Q

what can a pericardial effusion be secondary to?

A

pericarditis, uremia, or cardiac trauma

28
Q

what is cardiac tamponade?

A

when fluid compromises cardiac filling and impairs cardiac ouput

29
Q

what is the primary presenting sx of acute pericarditis?

A

sharp, pleuritic substernal radiating chest pain often relieved by sitting upright and leaning forward

30
Q

what is characteristic of PC?

A

cardiac friction rub

31
Q

how do constrictive pericarditis pts present?

A

slowly progressive dyspnea, fatigue, weakness, accompanied by edema, hepatomeglay, and ascites

32
Q

how do pericardial effusions present?

A

+/- pain, cough dyspnea

33
Q

how does cardiac tamponade present?

A

tachycardia, tachypnea, narrow pulse pressure, JVD. pulses paradoxus

34
Q

what is pulses paradoxus?

A

an abnormally large decrease in stroke volume, systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mmHg. When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus. Pulsus paradoxus is not related to pulse rate or heart rate and it is not a paradoxical rise in systolic pressure.

etect beats on cardiac auscultation during inspiration that cannot be palpated at the radial pulse.[1] It results from an accentuated decrease of the blood pressure, which leads to the (radial) pulse not being palpable and may be accompanied by an increase in the jugular venous pressure height (Kussmaul’s sign). As is usual with inspiration, the heart rate is slightly increased,[2] due to decreased left ventricular output.

35
Q

dx studies for pericarditis

A

CBC

cXR or echo- extent of effusion or pericardial clcification

36
Q

what would an EKG show in pericarditis?

A

diffuse ST-segment elevation

37
Q

what would an EKG show in effusion?

A

nonspecific T-wave changes and low WRS

38
Q

what is electrical alternans?

A

onsecutive, normally-conducted QRS complexes alternate in height.
the heart swings backwards and forwards within a large fluid-filled pericardium

massive pericardial effusions

39
Q

tx of pericarditis?

A

if pt is in hemodynamic compromise, do a pericardiaocentesis

may need a pericardial window

40
Q

inflammatory percarditis tx?

A

NSAIS or steroids

41
Q

constrictive pericarditis?

A

pericardectomy

42
Q

aortic aneurysm

A

weakness and subsequent dilation of vessel wall: genetic defect or atherosclerotic

43
Q

what ist he most common cause of aortic aneurysms?

A

artherosclerosis

but other causes include:
