Comparative Analysis of Early and Delayed Cardioprotective and Antiarrhythmic Efficacy of Hypoxic Preconditioning

Hypoxic preconditioning produces an infarct-limiting effect both in the early and delayed periods. The increase in heart resistance to ischemia-repefusion was more pronounced after early preconditioning. Hypoxic preconditioning did not change heart resistance to the arrhythmogenic effect of coronary occlusion and reperfusion.
