Atrial compliance determines the nature of passive atrial stretch and plasma atrial natriuretic factor in the conscious dog

Study objective — The aim was to measure changes in atrial wall function over a wide range of atrial filling pressures in order to determine the relationship governing the atrial stretch in vivo. Design — Acute graded haemorrhage, 30 ml·kg−1, was used to reduce atrial stretch, and volume loading wit...
