reduces friction when heart is beating
what is a complication of pericarditis
cardiac tamponade
what is cardiac tamponade
when the fluid surrounding the heart reaches 200 ml and compresses the heart and restricts its stretch and ability to fill with blood
- dec in cardiac output
what are signs of acute pericarditis
sharp chest pain that worsens with deep breath
fever
dyspnea
pericardial friction rub
ECG ST elevations
Becks triad
pulsus paradoxus
what are the s/s of cardiac tamponade
becks triad
- hypotension
- JVD
- muffled heart sound
what is pulsus paradoxus
a dec is systolic BP by about 10 mm Hg or more w inspiration
what is the treatment of pericarditis
NSAIDS
ASA
corticosteroids
colchicine –> when NSAIDs dont work
