The influence of fluid and diuretic administration on the index of atrial contribution in sequentially paced patients

Abstract

Aim was to examine whether acute changes in patient hydration can change atrial contribution (AC) to circulatory function. AC was examined in 24 paced patients by method using pulse oximetry signal at steady state and after furosemide.

Dehydration caused significant increase in AC.
