Tamponade Flashcards
(37 cards)
What happens to JVP waveform w/ tamponade?
Lose “Y” descent (RV filling loss)
Becks triad consist of?
D- Distended JVP
D- Distant Heart sounds
D- Decreased BP
What pulse is associated w/ tamponade?
Pulsus paradoxus
What is pulsus paradoxus?
> 10mmHG drop of SBP during NL inspiration
What can you expect on a EKG of tamponade or a very LRG effusion?
Electrical alternans
Low voltage
Electrical alternas is due to
Heart swinging back and forth beat to beat
Closer to chest then away
Why is echo beneficial for tamponade?
Can visualize cardiac chamber compression
What are inflammatory signs associated with pericarditis?
Pleuritic chest pain
Friction Rub
Fever +/-
Diffuse ST elevation
Tamponade + inflammatory signs is?
DX of acute idiopathic pericarditis
Large effusion w/ no inflammatory S/S or tamponade is?
Chronic idiopathic pericardial effusion
Tamponade w/out inflammatory S/S is?
Malignant effusion
DX tests/eval of tamponade include
Cardiac cath + same Dx tests as pericardial effusion
What is the benefit of performing a cardiac cath on a pt w/ tamponade?
Can directly measure intercardial/pericardial pressures
Causes of Exudates? M-PIC
M- Malignancy
P- Post-pericardiotomy
I- Infection
C- Collagen vascular DZ
Causes of transudate? HURT
H- Hypothyroidism
U- Uremia
R- Radiation
T- Trauma
Most important TXT of tamponade is? (2)
TXT underlying cause
Aggressive fluid management
What is pericariotomy?
Balloon used to create window for drainage
Difference between Tamponade and Constrictive PC?
Tamponade - Fluid under pressure
Constrictive PC - Scarred/rigid pericardium
What happens with impaired diastolic filling?
Elevated venous pressures > systemic & plum congestion
Impaired SV > Decreased CO
What are some common S/S between Tamponade and constrictive PC? “DR. PATHH”
D - Distended JVP R - Rales P - Peripheral Edema A - Ascites T - Tachycardia H - HOTN H - Hepatomegaly
What are the chronic inflammatory changes that happen w/ constrictive PC?
F- Fibrosis
A- Adherence
T- Thickening
C- Calcification
What does constrictive PC mimic?
R sided heart failure
What does constrictive PC essentially do to the heart filling?
Impairs diastolic filling WITHOUT effecting systolic filling
What are RHF S/S?
Increased Systemic venous pressure
Ascites
Hepatospleomegaly
Peripheral edema
