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

Group	Heart rate (BMP)	ST height (mV)	QT (ms)	P amplitude (mV)	R amplitude (mV)	T amplitude (mV)
Control	267.3 ± 32.4	20.5 ± 10.4	82.1 ± 21.3	2.61 ± 1.37	6.11 ± 1.74	1.98 ± 1.09
I/R	166.6 ± 30.8	280.7 ± 43.5	144.0 ± 35.4	5.77 ± 2.49	8.95 ± 2.17	3.87 ± 1.23
