Zusammenfassung

Purpose: Frame rates (FR) used for strain analysis assessed by speckle tracking in fetal echocardiography show a huge variation. Due to higher heart rates compared to adults, much higher FR are requested in fetuses. The aim of this study was to investigate the influence of the FR on strain analysis in two-dimensional (2D) speckle tracking. Material and methods: A prospective cross-sectional study was performed. Based on an apical or basal four-chamber view of the fetal heart, cine loops were acquired on a Toshiba Aplio 500 system. Each loop was digitally stored twice: firstly as a DICOM (digital imaging and comm…
