Table 1. dp/dtmax, Half Relaxation Time (HRT), and Force (Tension)–Frequency Relations
Data are expressed as mean ± SD (n = 8 for each group). Group assignment: see text. Normalized dp/dtmaxwas calculated by dividing dp/dtmaxby twitch tension.
* P < 0.05 versus group sham.
† P < 0.05 versus group sepsis.
‡ P < 0.05 for group sepsis–propofol 50 versus group sepsis–propofol 25.
dp/dtmax= maximum of the first derivative of developed pressure.
