Figure1 Measurement of AT and ET on the transaortic valve
Doppler tracing from different acoustic windows. 3C: apical 3 chamber
view, 5C: apical 5 chamber view, R: right parasternal approach. AT is
the period between the onset of transaortic flow and the peak of it. ET
is the period between the onset of transaortic flow and the termination
of it. For both AT and ET, 3 consecutive beats were measured and
averaged. cAT and cET were obtained by dividing AT and ET by square root
of R-R interval.
