Table 1 Comparison of data utilized by emergency physician vs. cardiologist for determination of diastolic dysfunction

From: Emergency physician use of tissue Doppler bedside echocardiography in detecting diastolic dysfunction: an exploratory study

Interpretation by Data collected Interpretation
Emergency physician TDI measurements mitral annulus (i.e., eʹS and eʹL) Average TDI velocities at mitral annulus (i.e., eʹA)
Sinus EKG rhythm strip Timing of early and late diastole
Cardiologist Clip of PSL view LV wall thickness estimation
Clip of apical 4-chamber view LA diameter
Mitral valve inflow velocities measurements (i.e., E and A) E/A ratio
E/eʹ to estimate LA pressure
TDI measurements mitral annulus (i.e., eʹS and eʹL) E/eʹ to estimate LA pressure
Sinus EKG rhythm strip Timing of early and late diastole
  1. TDI, tissue Doppler imaging; PSL, parasternal long, eʹs, mitral annulus downward velocity at the septum; eʹL, mitral annulus downward velocity at the lateral wall; eʹA, average mitral annulus downward velocity measured ([eʹS + eʹL]/2); E, peak mitral valve inflow velocity in early diastole; A, peak mitral valve inflow velocity in late diastole; LA, left atrium; LV, left ventricle
