Shock Step 1

Review Competency Goals for this Module:

  • Tamponade: Pericardial effusion (regardless of size); right atrial/RV diastolic collapse; associated findings of dilated, no collapsible IVC
  • Acute massive left sided valvular regurgitation: normal LV cavity size (acute valvulopathy); normal/hyperdynamic LV systolic function (LV volume overload); massive color Doppler regurgitant flow
  • Circulatory arrest during resuscitation: tamponade or acute cor pulmonale (from massive pulmonary embolism); LV systolic function (cardiac standstill vs severely depressed vs hypderdynamic); global LV systolic dysfunction
  • After successful resuscitation: heterogeneous contractility pattern suggestive of myocardial ischemia
