Fig. 11. Histograms depicting the ratio of the left atrial (LA) A loop to total pressure–volume diagram area (A/A + V;top ), the ratio of LA conduit to total reservoir volume (CV/RV;middle ), and LA–left ventricular (LV) coupling (Ees/ELV;bottom ) under baseline conditions and during the administration of 0.6, 0.9, and 1.2 MAC desflurane (solid bars), sevoflurane (open bars), or isoflurane (hatched bars). *Significantly (P < 0.05) different from CON; †significantly (P < 0.05) different from 0.6 MAC.
