Effects of preconditioned plasma collected during the late phase of remote ischaemic preconditioning on ventricular arrhythmias caused by myocardial ischaemia reperfusion in rats

  Figure 1.. Total duration of ventricular tachycardia in rat groups A1, A2 and A3. Data are shown as a box plot. The length of the box is the interquartile range and the median is represented by the horizontal bar inside the box. Error bars represent minimum and maximum outliers. The rats in groups A1, A2 and A3 received normal saline, non-preconditioned plasma, and preconditioned plasma, respectively, 1 h before myocardial ischaemia. There was no significant difference in the total duration of ventricular tachycardia among the three groups (P ≥ 0.05); Kruskal–Wallis test.

  Figure 2.. Total duration of ventricular fibrillation in rat groups A1, A2 and A3. Data are shown as a box plot. The length of the box is the interquartile range and the median is represented by the horizontal bar inside the box. There looks like no horizontal bar inside the box for groups A2 and A3 because that the median durations of ventricular fibrillation of the two groups are 0. Error bars represent minimum and maximum outliers. The rats in groups A1, A2 and A3 received normal saline, non-preconditioned plasma, and preconditioned plasma, respectively, 1 h before myocardial ischaemia. There was no significant difference in the total duration of ventricular fibrillation among the three groups (P ≥ 0.05); Kruskal–Wallis test.

  Figure 3.. Total duration of ventricular tachycardia in rat groups B1, B2, and B3. Data are shown as a box plot. The length of the box is the interquartile range and the median is represented by the horizontal bar inside the box. Error bars represent minimum and maximum outliers. The rats in groups B1, B2, and B3 received normal saline, non-preconditioned plasma, and preconditioned plasma, respectively, 24 h before myocardial ischaemia. There was no significant difference in the total duration of ventricular tachycardia among the three groups (P ≥ 0.05); Kruskal–Wallis test.

  Figure 4.. The total duration of ventricular fibrillation in rat groups B1, B2 and B3. Data are shown as a box plot. The length of the box is the interquartile range and the median is represented by the horizontal bar inside the box. Error bars represent minimum and maximum outliers. The rats in groups B1, B2, and B3 received normal saline, non-preconditioned plasma, and preconditioned plasma, respectively, 24 h before myocardial ischaemia. The total duration of ventricular fibrillation was shorter in group B3 compared with that seen in group B1. However, there were no significant differences in the total duration of ventricular fibrillation between groups B2 and B1 and between groups B2 and B3 (P ≥ 0.05). *P < 0.05 compared with group B3; Kruskal–Wallis test.
