本文报告了50例健康老年人心肺功能的测定数值,与有关成人数值比较结果,提示老年人心电图电轴左偏、低电压、心动过缓增多;心动超声图有主动脉根部内径、左室收缩期内径、右室内径、右室前壁数值增大,左室后壁厚度、EF 斜率、室间隔振幅减小;心电向量图横面及左侧面起始内量更向左后方;X 线心表面积>15%的增多,心胸比率>0.5的增多;肺功能有肺活量下降,残气及功能残气员增加,最大呼气中期流速下降;血气分析及酸碱平衡与成人效值相似. This article reports the measured values ​​of cardiopulmonary function in 50 healthy elderly people. Compared with the results of adults, it indicates that left axis, low voltage and bradycardia of the electrocardiogram in the elderly are increased. The aortic root diameter, left ventricular systole The diameter of the right ventricle and the anterior wall of the right ventricle increased, the thickness of the posterior wall of the left ventricle, the EF slope and the amplitude of the ventricular septum decreased; Heart rate increased> 15%, cardiothoracic ratio> 0.5 increased; lung function decreased lung capacity, residual capacity and functional residual increased, the maximum expiratory flow rate decreased; blood gas analysis and acid-base balance and adult efficacy similar.
