Question 9 How can ECHO be used to assess LV function? LV function can be assessed in the following ways Fractional shortening “Eyeballing“ of LVF Ejection fraction (EF) - Simpson method Stroke volume Systolic index of contractility dP/dt Longitudinal contraction using tissue Doppler MAPSE 1. Fractional shortening: Measures the “squeeze [...]
A 45 year old patient presents in cardiac arrest . What is the ultrasound approach to this patient? The approach to the patient in cardiac arrest is based on assessment of the 4 F's (fluid, form, function and filling) of the heart to assess for potentially reversible causes of cardiac [...]
