我们建立了家兔急性缺氧模型，用心导管方法测定左心室舒张功能指标，以进一步证实急性缺氧对左心室舒张功能的影响。为临床防治急性缺氧舒张功能障碍提供理论依据。1材料与方法家兔17只，体重2．5～3．5kg。分2组：缺氧1组（H1，n=12）吸入5％的低氧混合气、缺氧2组（H2，n=5 We established a rabbit acute hypoxia model, cardiac catheterization method to measure left ventricular diastolic function indicators to further confirm the impact of acute hypoxia on left ventricular diastolic function. Provide a theoretical basis for clinical prevention and treatment of acute hypoxia and diastolic dysfunction. 1 Materials and Methods 17 rabbits, weighing 2.5 ~ 3.5kg. Divided into two groups: hypoxia group 1 (H1, n = 12) inhaled 5% hypoxia mixture, hypoxia 2 group (H2, n = 5
