Echocardiographic Measurements in C57BL/6J Wildtype Mice after Cessation of Short-Term Pacing

	Sham-Paced, 6 hr (n = 6)	Paced, 6 hr (n = 6)
IDD, mm	3.1 ± 0.13 (0.3 ± 0.1)	3.2 ± 0.18 (0.1 ± 0.2)
IDS, mm	1.8 ± 0.12 (0.2 ± 0.1)	1.9 ± 0.12 (0.1 ± 0.2)
Fractional Shortening, %	43.8 ± 1.7 (-2.3 ± 1.7)	40.6 ± 2.4 (-1.1 ± 1.2)
AWTs, mm	1.2 ± 0.09 (-0.13 ± 0.13)	1.2 ± 0.12 (0.03 ± 0.08)
AWTd, mm	0.8 ± 0.07 (-0.07 ± 0.1)	0.8 ± 0.1 (0.07 ± 0.1)
PWTs, mm	1.6 ± 0.03 (-0.43 ± 0.08)	1.4 ± 0.16 (-0.43 ± 0.29)
PWTd, mm	1.0 ± 0.05 (-0.75 ± 0.12)	1.0 ± 0.13 (-0.42 ± 0.18)

Post-pacing data (and changes from pre-pacing baseline) are presented as group means ± SEM. Comparisons between groups were performed with unpaired T-tests. IDD, IDS, intraventricular dimensions at end-diastole, end-systole; AWTs, AWTd, anterior wall thicknesses at end-systole, end-diastole; PWTs, PWTd, posterior wall thicknesses at end-systole, end-diastole.
