What are the three types of Pericardial Dz?
|
Pericarditis, Pericardial constriction, and Tamponade.
|
|
|
4 types of "Dirt" for pericarditis?
Are etiologies always infectious? Sx? ECG findings? Tx? (3) |
Serofibrinous
- most common, plasma proteins Serous - mainly PMN, lymphocytes, Thin fluid Purulent - puss Hemorrhagic No, can be either infectous or non-infectous. - Pleuritic chest pain (may radiate to back) positional: worse lying down - fever Diffuse ST elevation: in random/varying leads... PR depression due to abnormal atrial depolarization NSAIDs, steroids, fluid drainage |
|
|
Which kind of pericardial dz limits the expansion of the ventricles, and inhibits transmission of thoracic pressure into pericardial space.
Effects? Sx? (2) Classic sign on PE? |
Constrictive.
Decreased PL because now the incoming blood rush with inspiration causes the RV to squish the LV. \CO --> fatigue, dizziness Venous congestion: Ascities, lower extremity edema JVP elevation with inspiration = Kussmaul's sign. |
|
|
Upon cardiac catheterization, which do you see on the Atrial wave form in constrictive pericarditis?
a-->x-->v-->y (this is the letter progression for the atrial wave form) How about on a RV/LV tracing? Inspiration/Expiration? Tx? |
"stadium analogy" w/o enough seats.
- blood rushes into fill ventricle, resulting in a steeper Y-wave descent. "Sqrt sign" (dip and plateau) in ventricle tracing. - there is a diastolic equalization of pressures - there is a rapid filling until the ventricle hits the rigid pericardium and stops. Inspiration increase RV pressure and decreases LV pressure b/c of previously discussed impingement. Remove pericardium. |
|
|
______ is basically an extreme form of cardiac constriction, resulting in extremely impaired ventricular filling.
See on PE? (give me the # mmHg drop necess for dx.) |
Cardiac Tamponade.
Pulsus paradoxis - decrease in systemic pressure with inspiration ***>10mmHg drop in sysP w/ inspiration = pulsus paradoxus |
|
|
In Cardiac tamponade, what is seen on the atrial pressure recordings?
Tx? |
- Blunted Y-descent b/c the blood cannot get into the left ventricle.
- diastolic equalization of pressure Pericardialcentesis |
