Table 3 Serial (repeated) measurement data (body weight, heart rate, vp, vp2/T, v′p, and v′m) from group 2 mice. Comparison of baseline data (D1 vs. D4; D1 vs. D7; D4 vs. D7) showed no significant differences. Comparison of post-dobutamine data also showed no significant differences except D1and D4 heart rates (*p < 0.05).
