Why the study?
Does volume loading alter left atrial systolic time intervals in patients with various heart diseases?
Does volume loading alter left atrial systolic time intervals in patients with various heart diseases?
Volume loading augments left atrial ejection via the Frank-Starling mechanism, decreasing both left atrial preejection period and ejection time due to increased preload and afterload.
No takes yet. Share an insight, caveat, or question.
Volume loading may shorten LA systolic intervals on echo in heart disease; leaves open validation for preload assessment or outcome prediction.
Okamoto et al. (1991) studied this question.
