TABLE 2.

Force and [Ca²⁺] transients in NTg, Tg-WT, and Tg-R145G intact papillary fibers

t_{50 (duration)} is the time from peak to 50% of force or Ca²⁺ in relaxation; t_10(duration) is the time from peak to 10% of force or Ca²⁺ in relaxation. Data are the mean of the n experiments ± S.E.

Mouse	Force transients		Ca2+ transients		n
	t50(duration)	t10(duration)	t50(duration)	t10(duration)
	ms	ms	ms	ms
NTg	79.0 ± 4.4	164.0 ± 12.4	165.8 ± 12.4	432.6 ± 9.3	5
Tg-WT	85.3 ± 4.3	180.4 ± 12.2	167.7 ± 6.8	489.7 ± 15.3	9
Tg-R145G	146.9 ± 9.0a	361.3 ± 13.3a	215.2 ± 5.0a	627.8 ± 13.4a	9

^aSignificantly different compared with Tg-WT and NTg (p < 0.05). There are no significant differences between Tg-WT and NTg.
