Systolic Function

Question 1

LV Systolic Indices

Methods/equations

Answer 1

FS (m-mode) = LVIDd-LVIDs/LVIDd *100%. Normal >26-45 Abnormal <25 
FAC (2D) = EDA-ESA/EDA * 100% 
Normal >40-60 Abnormal <40 
EF = EDV-ESV/EDV * 100% 
Normal >55 Abnormal <55 
MAPSE (lat): 10-14mm abnormal <8
TDI (lateral): >8cm/s (<5cm/s) 
MP index. MPI=(ICT+IRT)/ET 
Abnormal > 0.5 
dP/dt = 32mmHg / time  
Normal >1200 Abnormal < 800 
GLPSS, speckle tracking. 
Normal > (-) 20 aka more negative 
Abnormal < (-) 20 aka more positive
