Pericarditis Flashcards
What might a patient’s HPI include when suffering from pericarditis?
Prodrome, fever, malaise, myalgias Acute, sharp, stabbing chest pain Pain improved when leaning forward, worsened by lying supine Duration of hours to days Pleuritic pain
What are some exam findings suggestive of pericarditis?
Pericardial friction rub
New widespread ST elevation or PR depression on EKG
Where is a pericardial friction rub best heard?
with the diaphragm over the left sternal boarder
What percentage of pericarditis cases present with chest pain?
95%
How many stages of EKG changes might be seen with pericarditis?
four
What stage of EKG change is characterized by diffuse ST elevation?
Stage 1
What stage of EKG change is characterized by development of T-wave inversions?
Stage 3
What percentage of pericarditis patients may show up with atypical ECG changes?
40%
How does the ST segment in an ECG differ in morphology in pericarditis vs STEMI?
Pericarditis - ST elevation begins at the J point, rarely exceeds 5mm, normal concavity
STEMI - convex ST elevation may be more than 5mm in hight
How does distribution in an ECG differ in pericarditis vs STEMI?
Pericarditis - ST changes more generalized
STEMI - localized to vascular area of infarct
What are some differential diagnosis for pericarditis?
Acute MI Pneumonia with pleurisy Pulmonary embolism Aortic dissection Pneumothorax Cholecystitis Pancreatitis Esophageal inflammation
