Table 1

The ventricular arrhythmia score (VAS), the duration time of VT (VTt) and VF (VFt) in different groups at T₃ (𝑛=12, mean ± SD).

Group	VAS	VTt (s)	VFt (s)
C1	0.25±0.45	0	0
I/R1	4.67±0.49^∗	73.50±28.40^∗	16.67±14.62^∗
LX1	2.33±0.49^∗#	22.67±7.51^∗#	0

LX2	3.50±0.80^∗#Δ	35.42±14.92^∗#Δ	3.58±8.50^#

Note: T₃: during ligation of the left anterior descending coronary artery to reperfusion.
I/R₁ and LX₁ groups were compared with C₁ group, and I/R₂ and LX₂ were compared with C₂ group, ^∗𝑃<0.05.
LX₁ goup was compared with I/R₁ group, and LX₂ group was compared with I/R₂ group, ^#𝑃<0.05.
LX₂ group was compared with LX₁ group, ^Δ𝑃<0.05.
