Electrocardiographic parameters as calculated from the composite recordings in rats in vivo (n = 10).

Group	Heart rate (BMP)	ST height (mV)	QT (ms)	P amplitude (mV)	R amplitude (mV)	T amplitude (mV)
Control	356.1 ± 40.2	14.5 ± 10.7	76.7 ± 14.1	2.77 ± 1.53	6.04 ± 1.55	2.03 ± 1.02
I/R	236.5 ± 42.1	200.7 ± 33.2	105.4 ± 17.3	5.84 ± 2.58	8.82 ± 2.01	3.72 ± 1.17
PCr	313.1 ± 37.2^#	15.3 ± 12.6^###	80.2 ± 14.3^#	3.04 ± 1.65^#	6.22 ± 1.23^#	2.08 ± 1.04^#

Note:  < 0.05, < 0.01, < 0.001 versus the control group. ^# < 0.05, ^## < 0.01, ^### < 0.001 versus the I/R group. PCr group measurements were not all statistically significant, compared with the control group ( > 0.05).
