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.
