Change in LV relaxation and ejection times during (a-b) and immediately after (c-d) aerosol exposure. Day + 1 marks post-exposure day in ambulatory monitoring cages instead of exposure chambers. Air n = 3 and PEPs n = 4. Values calculated as mean (± standard error) of each animal’s change from its 4-day BL (mid-expo: 5 h/day, post-expo: 30 min/day). ^#P < 0.10 and *P < 0.05 vs. Air. BL means ± SEM for Air and PEPs groups, respectively: Ejection Time = 30.9 ± 0.5 and 31.3 ± 0.6 ms; and Relaxation Time = 47.4 ± 0.3 and 48.3 ± 0.3 ms
