Variable	CTR N = 12	CTR + S N = 12	SHAM N = 16	LVH N = 12	LVH + S N = 12
Body weight (g)	405.4 (27.1)	499.2** (41.4)	411.1 (29.1)	396.1 (45.0)	459.4* (29.1)
Heart weight (g)	1.04 (0.09)	1.18* (0.11)	1.07 (0.11)	1.09 (0.10)	1.12 (0.08)
LV weight (g)	0.48 (0.06)	0.60* (0.08)	0.48 (0.05)	0.57* (0.07)	0.59* (0.06)

Data are means (SD)
LV left ventricle, BW body weight
CTR, controls; SHAM, sham-operated controls; LVH, animals with pressure-overload-induced left ventricular hypertrophy
CTR + S, control animals subjected to electrically induced tachycardia; LVH + S, animals with pressure overload-induced LV hypertrophy subjected to electrically stimulated tachycardia
* P < 0.05 and ** P < 0.001 versus the appropriate controls (CTR or SHAM); $ P = 0.08 versus SHAM
