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

The Ultrasound Journal

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

Interpretation by	Data collected	Interpretation
Emergency physician	TDI measurements mitral annulus (i.e., eʹ_S and eʹ_L)	Average TDI velocities at mitral annulus (i.e., eʹ_A)
Emergency physician	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
	Mitral valve inflow velocities measurements (i.e., E and A)	E/eʹ to estimate LA pressure
	TDI measurements mitral annulus (i.e., eʹ_S and eʹ_L)	E/eʹ to estimate LA pressure
	Sinus EKG rhythm strip	Timing of early and late diastole

TDI, tissue Doppler imaging; PSL, parasternal long, eʹ_s, mitral annulus downward velocity at the septum; eʹ_L, mitral annulus downward velocity at the lateral wall; eʹ_A, average mitral annulus downward velocity measured ([eʹ_S + eʹ_L]/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
