Echocardiographic Findings in Cardiogenic Shock

Cause	IVC	LV size	LV contraction	RV size	RV contraction
LV dysfunction due to ischaemia	Normal or dilated	Large	Reduced regionally or globally	Normal	Normal (unless associated RV infarction)
Acute major pulmonary embolism	Dilated	Normal or small	Normal or increased	Large	Reduced
Cardiac tamponade	Dilated	Normal	Normal or increased	Normal	Diastolic free wall collapse
RV infarction	Dilated	Normal or large if associated LV inferior infarction	Normal or reduced if associated inferior infarction	Large	Reduced
