From: Respiratory influence on left atrial volume calculation with 3D-echocardiography
Mean end diastolic volume, end systolic volume, stroke volume and ejection fraction of the left atrium, during the different respiratory phases. Volumes are shown as mL’s and EF as %. Vertical lines are showing the standard deviations. No significant differences were found. EDV = end diastolic atrial volume, ESV = end systolic atrial volume, SV = atrial stroke volume, EF = atrial ejection fraction
